ABSTRACT:
A solid electrolytic capacitor having excellent electrical characteristics due to an insulating protective layer. A water-shedding silicone rubber that cures by moisture or heat energy is coated to form the insulating protective layer on a protruding portion of a valve metal foil, at a protruding portion on the end surface of a porous valve metal body and on the surface of a dielectric layer covering the protruding portion of the valve metal foil.
