PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolytic capacitor which performs electrolytic polymerization by turning on electricity between a positive electrode lead-out wire and a negative electrode plate without making flange-like burrs to be formed, and without causing a large leakage current to occur in a dielectric oxide film formed in a positive electrode body. SOLUTION: The method for manufacturing the solid electrolytic capacitor includes a process to form the dielectric oxide film in the sintered positive electrode body of metal powder penetrated by a rod-shaped metallic member and in a first protrusion of the metallic member; a process to expose the metallic member by removing at least a part of the dielectric oxide film formed in the first protrusion; a process to form by chemical polymerization a precoat layer composed of conductive polymer in the positive electrode body and the first protruding portion; a process to immerse the positive electrode body in an electrolytic polymerization liquid containing monomer, so that the first protruding portion of the metallic member is directed to the negative electrode plate arranged in a polymerization chamber; and a process to form a conductive polymer layer by electrolytic polymerization by turning on electricity between the metallic member and the negative electrode plate utilizing a second protruding portion of the metallic member.
