Abstract
Provided is a solid electrolytic capacitor comprising an anode of a porous body formed of a valve metal or its alloy, a dielectric layer formed on the surface in the inside part of the porous body and on the surface in the outer peripheral part thereof, a conductive polymer layer formed on the dielectric layer, a cathode layer formed on the conductive polymer layer in the outer peripheral part of the porous body, and an anode lead of which one end is embedded inside the anode, wherein the conductive polymer layer in the first region which is in the inside part of the porous body and the periphery around the anode lead as the center is formed of a polypyrrole layer, and the conductive polymer layer in the second region which is the periphery around the first region is formed by laminating a polypyrrole layer on a polyethylenedioxythiophene layer.
