Abstract:
1. A method for producing a solid electrolytic capacitor which comprises forming a dielectric layer on an anode body comprising a valve-acting metal sintered body having fine pores and forming a cathode comprising a conductive compound layer on the dielectric layer, wherein said step of forming the cathode comprises repeating a step of laminating the conductive compound layer on the dielectric formed on the anode body, which laminating step comprises dipping a part of the anode body to a predetermined depth into one of an inorganic compound solution, an organic compound solution or a conductive-polymer compound dispersion liquid, removing the anode body from the solution or dispersion to leave a liquid film on the anode body and drying the liquid film to form the conductive compound layer on the anode body to the predetermined depth, and increasing a depth that the anode body is dipped in the solution or dispersion liquid with each dipping, to thereby produce the solid electrolytic capacitor.
