An electronic component includes a component main body, an external electrode, and a protective member. The component main body has a lower surface. The external electrode includes a base layer. The base layer is in contact with the lower surface. The protective member is in contact with the lower surface and the base layer, is along an external edge of the base layer so as to surround the base layer, and does not project in a down direction below the lower surface.

A multilayer ceramic capacitor includes a multilayer body including an active portion and inactive portions, side margin portions, a first terminal electrode, and a second terminal electrode. The side margin portions include a first segregate including silicon as a main ingredient and having a longest dimension of about 10 nm or greater and about 50 nm or smaller, and second segregates including silicon as a main ingredient and having a longest dimension of about 1 m or greater.

A capacitor and an electronic device comprising same are disclosed. An electronic device according to the present disclosure may comprise: a substrate; a plurality of capacitors mounted on the substrate, each of the plurality of capacitors including a case extending to accommodate an electrolyte therein, and a cap coupled to one end of the case in the direction in which the case extends configured to restrict scattering of the electrolyte; and a fixing member comprising a protrusion and configured to press the perimeters of the caps in the radial direction of the caps to fix the plurality of capacitors to the substrate.
