Abstract:
A method for producing a solid electrolyte capacitor comprising the sequential steps of:forming an anode lead led out of an anode member; forming a dielectric film at a surface of said anode member by anodic oxidation to form a capacitor element; applying a water-repellent agent to a predetermined position of said anode lead; immersing said capacitor element in an oxidant solution of a mixture solvent of alcohol and water; drying said capacitor element; and immersing said capacitor element in an alcoholic solution of a conductive polymeric monomer to polymerize a conductive polymer electrolyte on a surface of said capacitor element by chemical oxidation, wherein the ratio of water to the mixture solvent of alcohol and water in said oxidant solution is 10 to 80 wt %.
