The winding start and winding end of the second winding are connected to the terminal electrodes in the other one of the two pairs.

An inductor manufacturing method includes making a coil with a wire member, the coil has two end portions, bending a dependent segment from one end portion of the coil, and bending a lateral extension from the dependent segment, bending a bent segment from the second end portion of the coil, and bending a lateral segment from the bent segment, a base member is then engaged into a space between the coil and the lateral extension and the lateral segment of the coil for forming a coil assembly, the coil assembly is then engaged into a mold cavity of a mold device and punched together with an iron powder, the lateral extension and the lateral segment of the coil are electroplated with an electroplating layer.

A coil component includes a core including a winding core portion, a first flange portion, and a second flange portion, and a first wire and a second wire that are wound around the winding core portion in the same direction and that form a winding portion. The winding portion includes a second intersecting portion along a third side surface of the winding core portion at a position on the winding portion nearest to the second flange portion.

A coil component comprising a core including a winding core having a shape extending in a constant direction, a first flange disposed at a first end in an extending direction of the winding core, and a second flange disposed at a second end in the extending direction of the winding core; first and second electrodes disposed on the first flange; third and fourth electrodes disposed on the second flange; and a coil including a first wire wound around the winding core and electrically connected to the first and third electrodes, and a second wire electrically connected to the second and fourth electrodes. The first and second flanges each have an inner surface facing the winding core, an outer surface facing toward the side opposite to the inner surface, a lower surface connecting the inner and outer surfaces, and an upper surface facing the side opposite to the lower surface.

A coil component has a structure capable of suppressing disconnection of a center wire material of a wire and reducing inconvenience due to deterioration of an insulating film. A slope is provided at a boundary portion between a mounting surface and an inner end face of a flange portion. A terminal electrode includes a first electrode portion provided along the mounting surface, and a second electrode portion provided along the slope so as to extend from a first electrode portion to the middle of the slope. A wire is electrically and mechanically connected in both the first electrode portion and the second electrode portion. A diameter of the wire on a winding core portion is larger than a dimension of the second electrode portion in a height direction, but a dimension of the slope in a depth direction is larger than the diameter of the wire.

A transformer without matching sleeve for wire winding operation comprises a transformer wire frame, an iron core, a first winding unit and a second winding unit. The transformer wire frame comprises a winding part, a first wire outlet part and a second wire outlet part. The winding part comprises a first baffle, the second wire outlet part comprises a first inclined surface, a first partition plate, and a first block, the first partition plate divides the second wire outlet part into a first winding area and a second winding area, the first partition plate is only arranged corresponding to the first winding area. The first block is positioned in the first winding area to divide the first winding area into an initial winding area and a series winding area. Therefore, when the second winding is wound, the isolation requirement can be met without matching a sleeve.
