Patent ID: 7988743

Claim:
A method for manufacturing a solid electrolytic capacitor, the method comprising: A) forming a capacitor element, including: A1) forming a manganese oxide layer on a surface of a dielectric oxide film layer in a cathode section of an anode body, the anode body being divided into an anode section and the cathode section; A2) forming conductive polymer as a solid electrolyte on the dielectric oxide film layer by chemically polymerizing a reaction solution containing a monomer, aromatic sulfonic acid, and a solvent using the manganese oxide layer as an oxidizing agent; and A3) forming a current collector layer on the solid electrolyte; B) connecting an anode terminal to the anode section of the anode body and connecting a cathode terminal to the current collector layer; and C) coating the capacitor element with an outer resin in such a manner that the anode terminal and the cathode terminal are partially exposed from the outer resin, wherein in the A2), polyhydric alcohol capable of being coordinated to manganese ions released from the manganese oxide layer is made to coexist with a chemical polymerization reaction.
