Abstract: A method for manufacturing an electrolytic capacitor includes: a first step of preparing a capacitor element including an anode having a dielectric layer; a second step of impregnating the capacitor element with a first processing solution including at least a conductive polymer and a first solvent; and a third step of swelling the conductive polymer after the second step, by impregnating the capacitor element with a second processing solution including a swelling agent while at least part of the first solvent remains in the capacitor element.
