Abstract
An electrolytic capacitor includes a cathode foil, an anode foil, a conductive polymer, and a liquid component. The anode foil has a dielectric layer on a main surface of the anode foil. The conductive polymer covers at least part of the dielectric layer. The conductive polymer is disposed between the cathode foil and the anode foil. The liquid component is in contact with the conductive polymer. The cathode foil includes a first oxide coating film on an end surface of the cathode foil.
