Abstract
A solid electrolytic capacitor is disclosed wherein use is made of an electrode produced by simultaneously forming an oxide film layer and a conductive polymer layer through electrolytic oxidation or other chemical treatments on a metal subjected to a surface roughening treatment, or forming a conductive polymer layer through plasma polymerization or other chemical treatments on a metal successively subjected to surface roughening and anodic oxidation treatments.
