The present invention provides a conductive polymer having high conductivity and excellent heat resistance, and a solid electrolytic capacitor and a conductive material which have low ESR and high reliability under high temperature conditions and have low leakage current. A conductive film having high properties and excellent heat resistance.na copolymer of styrenesulfonic acid and at least one non-sulfonic acid monomer selected from the group consisting of methacrylates, acrylates, and alkoxydecane compounds containing an unsaturated hydrocarbon or a hydrolyzate thereof In the presence of thiophene or a derivative thereof in water or an aqueous solution containing a mixture of water and a water-miscible solvent, a conductive polymer dispersion is obtained by oxidative polymerization, and the conductive polymer is used as a solid electrolyte. In the solid electrolytic capacitor, a conductive film is formed using the above conductive polymer. |
