Abstract:
An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body, a dielectric layer that covers at least a part of the anode body, a solid electrolyte layer that covers at least a part of the dielectric layer, and a cathode lead-out layer that covers at least a part of the solid electrolyte layer. The cathode lead-out layer includes a carbon layer and a silver-paste layer. The carbon layer is conductive and covers at least a part of the solid electrolyte layer. And the silver-paste layer covers at least a part of the carbon layer. The carbon layer contains carbon particles and silver.
