Abstract: A solid electrolytic capacitor includes anode, dielectric layer formed on anode, and conductive polymer layer formed on dielectric layer. A surface of dielectric layer is dotted with coupling particles. Conductive polymer layer covers coupling particles and is also in contact with dielectric layer. This enables to increase a self-repair capability for reducing leak current between the anode and a cathode in the solid electrolytic capacitor having the conductive polymer layer as a solid electrolytic layer.

Abstract: An electrolytic capacitor includes an anode, a dielectric layer formed on the anode, and an organic semiconductor layer covering at least a part of the dielectric layer. The organic semiconductor layer contains an organic semiconductor compound having a number average molecular weight of greater than or equal to 100 and less than or equal to 10,000 and a π electron cloud. In the organic semiconductor compound, a carrier moves between molecules of the organic semiconductor compound through the π electron cloud.
