Abstract
To provide a solid electrolytic capacitor having a high capacitance and an excellent heat resistance. A solid electrolytic capacitor includes: an anode; a dielectric layerprovided on the surface of the anode; a first conductive polymer layerprovided on the dielectric layer; a second conductive polymer layerprovided on the first conductive polymer layer; a third conductive polymer layerprovided on the second conductive polymer layer; and a cathode layer provided on the third conductive polymer layer, wherein the first conductive polymer layeris made of a conductive polymer film formed by polymerizing pyrrole or a derivative thereof, the second conductive polymer layeris made of a conductive polymer film formed by polymerizing thiophene or a derivative thereof, and the third conductive polymer layeris made of a conductive polymer film formed by electropolymerizing pyrrole or a derivative thereof.
