Abstract

A capacitor includes a first electrode and a second electrode arranged so that a main surface of the first electrode opposes a main surface of the second electrode, a first pseudo electrode layer disposed on the main surface of the first electrode, and a dielectric layer disposed between the first pseudo electrode layer and the main surface of the second electrode. The first pseudo electrode layer includes conductive particles electrically coupled to the first electrode.

Claims (11)

1. A capacitor comprising:

a first electrode and a second electrode arranged so that a main surface of the first electrode opposes a main surface of the second electrode;

a first pseudo electrode layer disposed on the main surface of the first electrode; and

a dielectric layer disposed between the first pseudo electrode layer and the main surface of the second electrode,

wherein the first pseudo electrode layer includes conductive particles electrically coupled to the first electrode, and

wherein the first pseudo electrode layer comprises a material having a dielectric constant equal to or larger than a dielectric constant of a material constituting the dielectric layer.

2. The capacitor according to claim 1 , further comprising a second pseudo electrode layer on the main surface of the second electrode, wherein the second pseudo electrode layer includes conductive particles electrically coupled to the second electrode.

3. The capacitor according to claim 2 , wherein the dielectric layer contains the conductive particles or ceramic particles.

4. The capacitor according to claim 1 , wherein the dielectric layer contains insulating particles.

5. The capacitor according to claim 2 , wherein the dielectric layer contains insulating particles.

6. The capacitor according to claim 3 , wherein the dielectric layer contains insulating particles.
