Abstract
A solid-state electrolytic capacitor reduces the possibility of failure due to increasing of a leakage current during application of voltage for a long period and thus improves reliability. The solid-state electrolytic capacitor has a conductive high polymeric compound deposited on a dielectric oxidation layer covering the surface of pore in a tantalum plate while maintaining voids. The void surface acts as an oxygen supply source.
