ELECTROLYTIC CAPACITOR MANUFACTURING METHOD AND ELECTROLYTIC CAPACITOR

摘要

This electrolytic capacitor manufacturing method involves a step for preparing a positive electrode body having a dielectric film, a step for preparing a first liquid composition containing a first conductive polymer, a step for impregnating the positive electrode body with the first liquid composition and thereafter drying the same to form a capacitor element that has a solid electrolyte layer disposed on the surface of the dielectric film and containing the first conductive polymer, a step for preparing a second liquid composition that contains a non-aqueous solvent and a second conductive polymer dissolved in the non-aqueous solvent, a step for impregnating the capacitor element with the second composition, and a step for housing the capacitor element impregnated with the second liquid composition in an exterior case.
