Patent ID: 8206467

Claim:
A method for manufacturing a solid electrolytic capacitor, comprising the steps of: forming a porous anode body; forming a dielectric layer on a surface of the anode body; soaking the anode body having the dielectric layer in a liquid containing a conductive-polymer monomer; forming a first conductive polymer layer on the dielectric layer by soaking the anode body that has been soaked in the liquid containing the conductive-polymer monomer in an oxidizing agent solution, thereby polymerizing the monomer by liquid-phase chemical polymerization; forming a second conductive polymer layer on the first conductive polymer layer by holding the anode body having the first conductive polymer layer in a vapor of a conductive-polymer monomer, thereby polymerizing the monomer by gas-phase chemical polymerization; and forming a third conductive polymer layer on the second conductive polymer layer by soaking the anode body having the second conductive polymer layer in a liquid containing a conductive-polymer monomer, thereby polymerizing the monomer by electrolytic polymerization.
