Abstract: A disclosed manufacturing method is a method for manufacturing an electrolytic capacitor that includes an anode foil having a dielectric layer formed on a surface thereof, a cathode foil, and a separator. The manufacturing method includes, in the following order: a polymer layer formation step of forming a conductive polymer layer containing a conductive polymer component on the separator and at least one surface selected from a surface of the dielectric layer and a surface of the cathode foil; a stacked body formation step of forming a stacked body by stacking the anode foil, the cathode foil, and the separator; a liquid application step of impregnating the conductive polymer layer included in the stacked body with a liquid that includes water and an organic compound that does not boil at 100° C. under 1 atm; a removal step of removing a portion of the liquid with which the conductive polymer layer has been impregnated, such that the organic compound remains in the conductive polymer layer; and an impregnation step of impregnating the stacked body subjected to the removal step with a liquid component.

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.
