Abstract

A capacitor includes multiple capacitor elements including a first end surface electrode and a second end surface electrode; a first conductor in contact with and electrically connected to the first end surface electrode; a second conductor in contact with and electrically connected to the second end surface electrode; a third conductor adjacent to the first conductor, the third conductor including an embedded part positioned in a first section that overlaps with the first conductor and an exposed part positioned in a second section separate from the first section; and a sealing resin part sealing the third conductor to embed the embedded part and expose the exposed part.

Claims (24)

1 . A capacitor, comprising:

a plurality of capacitor elements each including

a first end surface electrode positioned on a first end surface and corresponding to a first polarity, and

a second end surface electrode positioned on a second end surface and corresponding to a second polarity;

a first conductor in contact with and electrically connected to the first end surface electrode;

a second conductor in contact with and electrically connected to the second end surface electrode;

a third conductor adjacent to and electrically connected to the first conductor, the third conductor including

an embedded part positioned in a first section that overlaps with the first conductor in a plan view seen from the first end surface electrode toward the second end surface electrode, and

an exposed part positioned in a second section separate from the first section; and

a sealing resin part sealing the plurality of capacitor elements, the first conductor, and the second conductor, the sealing resin part sealing the third conductor to embed the embedded part and expose the exposed part.

2 . The capacitor according to claim 1 , wherein

the first conductor includes a first fastening part, and

the third conductor includes a second fastening part fastened to the first fastening part.

3 . A capacitor, comprising:

a plurality of capacitor elements each including

a first end surface electrode positioned on a first end surface and corresponding to a first polarity, and

a second end surface electrode positioned on a second end surface and corresponding to a second polarity;

a first conductor in contact with and electrically connected to the first end surface electrode, the first conductor including a first fastening part;

a second conductor in contact with and electrically connected to the second end surface electrode;

a third conductor adjacent to the first conductor, the third conductor including

an embedded part positioned in a first section that overlaps with the first conductor in a plan view seen from the first end surface electrode toward the second end surface electrode,

an exposed part positioned in a second section separate from the first section, and

a second fastening part fastened to the first fastening part; and

a sealing resin part sealing the plurality of capacitor elements, the first conductor, and the second conductor, the sealing resin part sealing the third conductor to embed the embedded part and expose the exposed part.
