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.
