Abstract:
A method of manufacturing a solid electrolytic capacitor, comprising the steps of:forming an oxide film as a dielectric layer on a surface of a sintered body formed from a valve action metal and having an anode lead; andforming a solid electrolytic layer essentially consisting of a conductive polymer on the dielectric layer,wherein the step of forming the solid electrolytic layer comprises the steps ofdipping the sintered body having the dielectric layer in an oxidant solution and evaporating the oxidant solution on the surface of the sintered body, anddipping the sintered body in a monomer solution prepared by dissolving a conductive polymeric monomer in a solution in which the oxidant is not dissolved, and evaporating the monomer solution on the surface of the sintered body to form the conductive polymer layer.
