An electrolytic capacitor including a capacitor element. The capacitor element includes an anode body, a dielectric layer covering at least a part of the anode body, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The cathode lead-out layer includes a conductive layer. An oxygen permeability of the conductive layer at a thickness of 10 μm is less than or equal to 7 cc/m2·day·atm.
