Abstract: PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor having excellent moisture-proof characteristic that can increase electrostatic capacitance and reduce ESR. SOLUTION: The solid electrolytic capacitor is constituted by forming a dielectric material oxide film on a plate-type valve metal on an expanded surface to be used as an anode, forming a first conductive polymer layer by chemical polymerization on the oxide film, and forming a second conductive polymer layer on the first conductive polymer layer by soaking the same layer into the conductive polymer compound dispersed solution or coating the same solution to the same layer. In this solid electrolytic capacitor, a binder layer is formed between the first and the second conductive polymer layers. Moreover, as the conductive polymer compound dispersed solution, a dispersed solution is used as mixing the powder of conductive polymer compound and the predetermined binder.
