Abstract
A solid electrolytic capacitor according to the present disclosure includes at least one capacitor element. The capacitor element includes an anode body including a porous part at least at a surface layer, a dielectric layer covering a surface of the anode body, and a solid electrolyte layer covering at least a part of the dielectric layer. The solid electrolyte layer has a first portion filled in voids of the porous part in the anode body having the dielectric layer, and a second portion disposed on an outer surface of the anode body having the dielectric layer. The first portion contains a self-doping conductive polymer, and the second portion containing a non-self-doping conductive polymer.
