Abstract
An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body, a dielectric layer disposed on a surface of the anode body, a solid electrolyte layer covering at least a part of the dielectric layer, and a first layer covering at least a part of the solid electrolyte layer. The first layer is in contact with the solid electrolyte layer. The first layer constitutes at least a part of the cathode lead-out layer. An electrode potential Pof the solid electrolyte layer is higher than an electrode potential Pof the first layer.
