Embodiments of the present disclosure relate to an inductor and an electronic device including the same. An inductor, according to one embodiment of the disclosure, can include a magnetic body, a coil located in the magnetic body, a first electrode located on a first portion of the magnetic body and electrically connected to one end of the coil, a second electrode located on a second portion of the magnetic body and electrically connected to another end of the coil, a radiation pattern located on a first surface of the magnetic body, and a third electrode located on a third portion of the magnetic body and electrically connected to the radiation pattern.

An inductive device and a method of manufacturing the same are provided. The inductive device includes a magnetic base, a coil structure, and a package structure. The magnetic base includes a bottom plate, a core column, and a lateral wall defining a positioning trench. The coil structure includes a coil body, a first extending section, and a second extending section. The coil body disposed in the positioning trench surrounds the core column. The first extending section includes a first bent portion and a first terminal portion connected at a first connecting point. The second extending section includes a second bent portion and a second terminal portion connected at a second connecting point. A shortest distance between a first imaginary connection line defined between the first and second connecting points and a central axis of the core column is less than a minimum outer radius of the coil body.

The inductor includes a coil including a winding portion formed by winding a conductor wire having an insulating coating and lead-out portions extended from the winding portion, and a body made of a magnetic portion including magnetic powder and resin, and containing the coil, and outer electrodes on a body surface. The body includes a mounting surface, an upper surface opposite the mounting surface, a pair of opposing end surfaces adjacent to the mounting and upper surfaces, and a pair of opposing side surfaces adjacent to the mounting surface, the upper surface, and the end surfaces. End portions of the lead-out portions respectively have a flat portion exposed from the body surface, a covered portion adjacent to the flat portion at at least one of the end portions covered with the magnetic portion, and the flat portion is electrically connected to the outer electrode.

In an electronic component, a terminal electrode has a thickest portion and a part thinner than the thickest portion. Accordingly, an increase in solder fillet forming region occurs when the electronic component is solder-mounted onto a predetermined mounting substrate. In the electronic component, mounting strength is improved as a result of the increase in solder fillet forming region. In addition, in the electronic component, the thickest portion overlaps a bump electrode in a direction orthogonal to the lower surface of an element body. Accordingly, the impact that is applied to the electronic component during the mounting onto the mounting substrate is reduced and the impact resistance of the electronic component is improved.

A coil component is provided. The coil component includes a body having one surface and the other surface, opposing each other, and including a plurality of wall surfaces respectively connecting the one surface and the other surface, a coil portion embedded in the body, first and second external electrodes spaced apart from each other on one surface of the body, and respectively connected to the coil portion, a groove formed continuously along an edge of the other surface of the body, and a stress relieving portion disposed on the other surface of the body to fill at least a portion of the groove.

A magnetic material and an inductor capable of attaining both higher magnetic permeability and improved DC superposition characteristics. A composite magnetic material contains metal magnetic particles, in which the metal magnetic particles include first particles having a median diameter D.sub.50 of 1.3 μm or more and 5.0 μm or less (i.e., from 1.3 μm to 5.0 μm), and second particles having a median diameter D.sub.50 larger than the first particles. The first and second particles each include a core portion made of a metal magnetic material, and an insulating film provided on a surface of the core portion. The insulating film of the second particles has an average thickness of 40 nm or more and 100 nm or less (i.e., from 40 nm to 100 nm). The insulating film of the first particles has an average thickness smaller than that of the insulating film of the second particles.

An inductor in which the external electrode is constituted by a conductive resin layer formed on a surface of a core effectively prevents peeling between the core and the external electrode. The inductor includes a core containing magnetic particles and a resin, a conductor embedded in the core, a conductive resin layer disposed on a surface of the core so as to be in contact with an end portion of the conductor exposed from the core, and a plating layer formed on the conductive resin layer. The plating layer is formed so as to extend to the surface of the core beyond a range in which the conductive resin layer is disposed.

A coil component includes a support substrate, a coil portion including a first conductive layer being in contact with one surface of the support substrate, and a second conductive layer disposed on the first conductive layer to be spaced apart from the one surface of the support substrate, and a body including the support substrate and the coil portion embedded in the body. One side of the first conductive layer is closer to a center of the second conductive layer in a width direction of the coil portion than one side of the second conductive layer.

In the coil component, since the contact area between the external terminal electrode and the element body is increased by the protrusion of the external terminal electrode, the external terminal electrode and the element body are more closely attached to each other. Therefore, the attachment strength between the external terminal electrode and the element body can be improved. Hence, it is possible to suppress peeling of the external terminal electrode from the element body.

A coil component includes a body having one surface and the other surface opposing each other and including a magnetic metal powder particle and an insulating resin; a coil portion embedded in the body and having end portions respectively exposed from end surfaces of the body; first and second external electrodes arranged to be spaced apart from each other on the one surface and extending to the end surfaces to be connected to the end portions, respectively; and an external insulating layer disposed between each of the first and second external electrodes and the one surface of the body. A magnetic metal powder particle exposed on the wall surface of the body, among the magnetic metal powder particle, has a plating prevention film disposed on at least a portion of a surface of the exposed magnetic metal powder particle and including metal ions of the magnetic metal powder particle.
