Abstract
A solid electrolytic capacitor that can be miniaturized while maintaining the function for breaking current when excessive short-circuit current flows to a capacitor element. The solid electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, a conductive polymer layer formed on the dielectric layer, and a cathode layer formed on the conductive polymer layer. The conductive polymer layer contains thermally expandable graphite.
