Abstract
An electrolytic capacitor includes a capacitor element that includes a porous anode body including an anode base body and a dielectric layer formed on a surface of the anode base body, and a solid electrolyte layer that covers at least a part of the dielectric layer. The anode body includes a plurality of principal surfaces, and at least a part of a surface layer of at least one principal surface of the plurality of principal surfaces of the anode body is denser than an inside of the anode body.
