摘要： A method includes the following steps: forming a porous anode body using powder of valve metal or an alloy thereof; forming a dielectric layer on the surface of the anode body; soaking the anode body having the dielectric layer in a liquid containing a conductive-polymer monomer, thereby making the monomer adhere to the dielectric layer of the anode body; forming a first conductive polymer layer by soaking the anode body having the monomer adhered thereto in an oxidizing agent solution, thereby polymerizing the monomer by liquid-phase chemical polymerization; forming a second conductive polymer layer by bringing the conductive-polymer monomer into contact with the surface of the anode body having the first conductive polymer layer in a gas phase, thereby polymerizing the monomer by gas-phase chemical polymerization; and forming a third conductive polymer layer by soaking the anode body having the second conductive polymer layer in a liquid containing a monomer of a conductive polymer layer, thereby polymerizing the monomer by electrolytic polymerization.

摘要： A solid electrolytic capacitor has an anode body including a porous sintered body consisting of a valve action metal, a dielectric layer deposited on a surface of the anode body, a conductive polymer layer deposited on a surface of the dielectric layer, and a cathode layer deposited on a surface of the conductive polymer layer. The conductive polymer layer includes a laminated film consisting of a first conductive polymer layer formed by a chemical polymerization process and a second conductive polymer layer formed by an electrolytic polymerization process. The first conductive polymer layer has recesses on its surface against the dielectric layer. Interior surfaces of such recesses define cavities which constitute pores at an interface between the first conductive polymer layer and the dielectric layer. These pores are distributed at intervals along the interface between the first conductive polymer layer and the dielectric layer in such a way that the dielectric layer is exposed to their interior surfaces.
