ABSTRACT:
A solid electrolytic capacitor includes an anode, a dielectric layer, two conductive polymer compound layers, and a cathode electrode. The anode consists of a valve metal and has a lead extending therefrom. The dielectric layer is formed by oxidizing a surface of the anode. The two conductive polymer compound layers are formed on the dielectric layer and respectively consist of solid electrolytes, at least one of the two conductive polymer compound layers consisting of a conductive polymer compound chemically oxidized and polymerized using an oxidant. The cathode electrode is formed on the two conductive polymer compound layers. A method of manufacturing this capacitor is also disclosed.
