ABSTRACT:
Disclosed is a method for manufacturing a solid electrolytic capacitor in which a capacitor element has conductive polymer solid electrolyte on a dielectric oxide film layer. The method includes the following processes: forming a manganese oxide layer on the dielectric oxide film layer; and chemically polymerizing a reaction solution containing a monomer, aromatic sulfonic acid, and a solvent using the manganese oxide layer as an oxidizing agent. Here, polyhydric alcohol capable of being coordinated to manganese ions released from the manganese oxide layer is made to coexist with the chemical polymerization reaction.
