摘要

A capacitor includes a structure including a plurality of openings penetrating from a first surface of the structure to a second surface opposing the first surface; a capacitor layer disposed on the second surface of the structure and in the plurality of the openings and including a dielectric layer, and a first electrode and a second electrode, the dielectric layer interposed between the first electrode and the second electrode; a first connection layer disposed on the first surface of the structure and connected to the first electrode; a second connection layer disposed on the capacitor layer on the second surface and connected to the second electrode of the structure; and first and second terminals disposed on opposite side surfaces of the structure and connected to the first connection layer and the second connection layer, respectively.

Hereinafter, the structure 110 in which the capacitor layer 120, the first connection layer 140, and the second connection layer 150 are disposed is referred to as a body.

Additionally, the capacitor according t an exemplary embodiment in the present disclosure may include a protective layer 180. The protective layer 180 may be disposed to surround the body other than the side surfaces on which the first terminal 160 and the second terminal 170 are disposed. The protective layer 180 may be formed of a polymer material, for example, a polymer resin such as epoxy, but is not limited thereto. The protective layer 180 may protect the capacitor from external impact or conductive foreign materials.

The first terminal 160 and the second terminal 170 may be disposed on opposite side surfaces of the body.

Since the first terminal 160 is connected to the first connection layer 140 exposed to the first side surface of the body, the first terminal 160 may be electrically connected to the first electrode 121. In addition, since the second terminal 170 is connected to the second connection layer 150 exposed to the second side surface of the body, the second terminal 170 may be electrically connected to the second electrode 122. The first terminal 160 and the second terminal 170 may be implemented to have a low resistance value using copper, a copper alloy, or the like, and may be formed by a paste printing process.
