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 a conductive polymer and a first solvent; and a third step of impregnating the capacitor element with an electrolyte solution after the second step, the capacitor element being, in the third step, impregnated with the electrolyte solution while including a liquid.

A method for producing an electrolytic capacitor, the method comprising:
- 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 a conductive polymer and a first solvent;
- and
- a third step of impregnating the capacitor element with an electrolyte solution after the second step,
- wherein the capacitor element is, in the third step, impregnated with the electrolyte solution while the first solvent is remaining in the capacitor element.
