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.

Abstract: A method for producing an electrolytic capacitor according to the present disclosure includes a first step of preparing a capacitor element that includes an anode body having a dielectric layer; a second step of impregnating the capacitor element with a first treatment solution containing at least a conductive polymer and a first solvent; and a third step of impregnating, after the second step, the capacitor element, in which at least a part of the first solvent remains, with a second treatment solution containing a coagulant to coagulate the conductive polymer.
