Abstract

The present invention relates to a solid electrolytic capacitor comprising an electrode produced by forming a solid electrolytic layer comprised by a polymer having at least one repeating unit selected from a thiophene-diyl skeleton, an isothianaphthene-diyl skeleton, a pyrrole-diyl skeleton, a furan-diyl skeleton and an iminophenylene skeleton and having a fibril structure on a dielectric film layer of a porous valve-acting metal and its production method, and to a highly electroconductive polymer obtained by chemical oxidative polymerization of a monomer and an oxidizing agent at an interface and its production method.
