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

Abstract: A power storage device includes an electricity storage element, a case, and a sealing member which includes an elastic member. The elastic member contains an elastic polymer and a hindered phenol compound. The hindered phenol compound having a phenol skeleton includes a first hindered group and a second hindered group. The first hindered group is bonded to a first substitution site of the phenol skeleton, and the second hindered group is bonded to a second substitution site of the phenol skeleton. Each of the first substitution site and second substitution site is adjacent to a substitution site of the phenol skeleton to which a phenolic hydroxy group is bonded. One of one or more tertiary carbon atoms in the first hindered group and one of one or more tertiary carbon atoms in the second hindered group are bonded to the first substitution site and the second substitution site, respectively.
