Abstract
Abstract A solid electrolytic capacitor with a charge transfer complex disposed in place of the usual electrolyte (paste or manganese dioxide), the acceptor being an organic substance having oxidizing property against aluminum, tantalum etc. and the donor being selected so as to decrease the resistivity of the complex compound as much as possible; the characteristic being that through the use of the organic semiconductor electrolyte the self-healing of oxide film is made possible.
