(57) [Abstract] [Purpose] An object of the present invention is to provide a method for manufacturing an aluminum electrolytic capacitor, which has little deterioration in performance, high withstand voltage, and excellent in ionic conductivity, equivalent series resistance, and tan δ. [Structure] A capacitor element in which hydroxyethyl (alkyl) cellulose is attached to at least one of the anode foil, cathode foil and separator is brought into contact with a driving electrolyte solution containing a polyhydric alcohol solvent to gel the driving electrolyte solution. By doing so, an aluminum electrolytic capacitor is manufactured. |
