Abstract: A method for manufacturing an electrolytic capacitor according to the present disclosure includes a first step to a third step described below. The electrolytic capacitor includes an anode body having a dielectric layer, and a solid electrolyte layer formed on a surface of the dielectric layer. The first step is a step of preparing a first treatment solution by dissolving or dispersing a conductive polymer in a liquid first component and leaving a conductive polymer solution or a conductive polymer dispersion liquid to stand for a first period. The second step is a step of preparing a second treatment solution by mixing the first treatment solution with a second component. The third step is a step of forming a solid electrolyte layer on a surface of the dielectric layer by applying the second treatment solution to the surface of the dielectric layer.
