An anode foil and a cathode foil which has an oxidation film layer on the surface are separated by a separator and wound to form a capacitor element and then anodic forming is performed on this capacitor element. Next, the capacitor element is immersed in a solution of less than 10 wt%, preferably between 2.0 and 9 wt%, more preferably between 5 and 8 wt% of polyimide silicone dissolved in a ketone solvent, and after removing, the solvent is evaporated off at between 40 and 100 DEG C and heat treating is performed at 150 to 200 DEG C. Next, this capacitor element was immersed in a mixture of polymeric monomer and oxidizing agent and the conductive monomer was made to polymerize in the capacitor element to form a solid electrolyte layer. Furthermore, this capacitor element was stored in an external case and the open end was sealed with sealing rubber to form the solid electrolytic capacitor. <IMAGE> |
