Abstract
First, an anode lead is led out of an anode member. Next, a dielectric film is formed at a surface of the anode member by anodic oxidation to form a capacitor element. Thereafter, a water-repellent agent is applied on a predetermined position of the anode lead. In succession, the capacitor element is immersed in an oxidant solution of a mixture solvent of alcohol and water, followed by drying. The capacitor element is then immersed in an alcoholic solution of a conductive polymeric monomer to polymerize a conductive polymer electrolyte on a surface of the capacitor element by chemical oxidation.
