ABSTRACT:
A method for manufacturing a solid electrolytic capacitor having a capacitor element produced by the steps of: forming a dielectric coating layer on the surface of an anode body, forming a conductive polymer cathode layer on the dielectric coating layer, and forming a cathode lead-out layer on the conductive polymer cathode layer, wherein the step of forming the conductive polymer cathode layer includes an electrolytic polymerization step of forming the conductive polymer cathode layer on the surface of the anode body on which the dielectric coating layer is formed by electrolytic polymerization using an electrolytic polymerization solution containing at least a monomer to be polymerized into the conductive polymer and an ionic liquid.
