The method for manufacturing an electrolytic capacitor of the present invention includes a first step of preparing a capacitor element including an anode body on which a dielectric layer is formed, and a first process in which the capacitor element includes a first solvent and a conductive polymer. A second step of impregnating a liquid, a third step of impregnating the capacitor element with a second treatment liquid containing a second solvent after the second step, and a capacitor element after the third step, And a fourth step of impregnating an electrolytic solution containing a third solvent, wherein the second solvent and the third solvent are both protic solvents. |
