SOLID ELECTROLYTIC CAPACITOR AND MANUFACTURING METHOD THEREFOR

摘要

A solid electrolyte capacitor in which a valve-acting metal substrate with a dielectric oxide film formed on the surface of an anode body is immersed alternately in a monomer solution and an oxidant solution to form a first conductive polymer layer on the surface of the dielectric oxide film. Thereafter, the capacitor element with the first conductive polymer layer is immersed in a soluble conductive polymer solution or a conductive polymer suspension to form a second conductive polymer layer that varies little in film thickness. Then, a cathode layer is formed on the conductive polymer layer.
