Abstract
A solid electrolytic capacitor includes an anode body formed with a dielectric oxide film, a laminate cathode provided on the dielectric oxide film, a cathode lead frame provided on the cathode, and an anode lead frame attached to a lead portion of the anode body. The laminate cathode includes a solid electrolyte layer, and a mixture layer of a mixture of silver flake particles and carbon particles provided directly on an outer surface of the solid electrolyte layer.
Claims5
