PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolytic capacitor capable of further reducing ESR. SOLUTION: Anode foil having an oxide film layer formed on the surface and cathode foil are wound via a separator, a capacitor element is formed, and repairing formation is applied to the capacitor element. Subsequently, the capacitor element is dipped into a polymerizable monomer solution, is pulled up for drying, and is dipped into an oxidant solution for generating the polymerizing reaction of a conductive polymer in the capacitor element to form a solid electrolytic layer. At this point, the mole ratio of the monomer after dipping to the oxidant is set to be less than 3:1, when the oxidant is set to 1. Then, the capacitor element is inserted into an encapsulating case, and a sealing rubber is attached to an opening end for sealing by caulking work before aging is made, thus forming the solid electrolytic capacitor.
