METHOD FOR PRODUCING ELECTROLYTIC CAPACITOR

摘要

This method for producing an electrolytic capacitor is characterized by including: a first step for preparing a capacitor element provided with a positive electrode body having a dielectric layer; a second step for impregnating the capacitor element with a first process liquid containing at least a first solvent and a conductive polymer; and, after the second step, a third step for impregnating the capacitor element with a second process liquid containing a swelling agent in the state of at least a portion of the first solvent remaining, thus swelling the conductive polymer.
