METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrolytic capacitor which allows the occurrence of short-circuit to be suppressed in a so-called hybrid type electrolytic capacitor.SOLUTION: A method for manufacturing an electrolytic capacitor comprises the steps of: forming a capacitor element 12 having a positive electrode foil 12A having a dielectric layer on a surface thereof, and a solid electrolytic layer 122 in contact with the dielectric layer 121 of the positive electrode foil 12A; impregnating the capacitor element 12 with an electrolytic solution 16; and sealing the capacitor element 12 together with the electrolytic solution 16 in an outer sheath 15. The electrolytic solution 16 impregnated into the capacitor element 12 includes a first solvent including polyalkylene glycol or a derivative thereof.
