Abstract: A method for manufacturing an electrolytic capacitor includes a first connection step, a second connection step, a first insertion step, a housing step, and a sealing step. In the first connection step, a first internal lead having a foil shape is connected to a first electrode foil. In the second connection step, after the first connection step, a first external lead having a rod shape is connected to the first internal lead to obtain the first electrode. In the first insertion step, the first external lead is inserted into an insertion port of a sealing plate after the second connection step. In the housing step, the first electrode is housed in a container after the first insertion step. In the sealing step, an opening of the container is closed with the sealing plate after the housing step.

Abstract: An electrolytic capacitor includes a capacitor element, a liquid component, a case housing the capacitor element and the liquid component, and a sealing member sealing the case. the capacitor element includes a porous sintered body including a dielectric layer, a cathode foil facing at least a part of the porous sintered body, and a conductive polymer covering at least a part of a surface of the dielectric layer. The conductive polymer is in contact with the cathode foil. And a void in the capacitor element is impregnated with the liquid component.
