Abstract:
An electrolytic capacitor includes a capacitor element; a bottomed case that houses the capacitor element; a sealing member that seals an opening of the bottomed case; a tab terminal connected to the capacitor element and penetrating through the sealing member; and a resin layer that covers at least part of a main surface of the sealing member, the main surface being disposed outside the bottomed case. The tab terminal includes a first portion containing a first metal and a second portion containing a second metal. The resin layer is in contact with the first portion and the second portion. Linear expansion coefficient α1 of the first metal, linear expansion coefficient α2 of the second metal, and linear expansion coefficient αr of the resin layer satisfy a relation of α1
