Abstract:
To provide an electrolytic capacitor with improved reliability. The electrolytic capacitor including: at least one capacitor element including an anode foil having a first part including a first end, and a second part including a second end, a dielectric layer formed on at least a surface of the second part, and a cathode part covering at least part of the dielectric layer; a package body enclosing the capacitor element; and an external electrode. At least a surface of the second part has a porous portion, and at least an end face of the first end is exposed from the package body and is in contact with the external electrode.
