Abstract: The present invention includes an outer package and contents accommodated in the outer package. The contents include an electrode body. The outer package substantially uniformly applies pressing force to each of the front surface and the rear surface of the contents due to the elastic force of the outer package.

Abstract: A terminal-equipped case member having an external terminal for electrically connecting an external device, which is fixed to a case body for housing an electronic component or a case member constituting a case lid attached to the case body, includes a base material made of metal that forms the case member; the external terminal inserted into a through hole formed through the base material; a sealing material formed of a first resin material that seals a gap between the external terminal and the base material; and a terminal adhesion layer. The external terminal and the sealing member are bonded to each other through the terminal adhesion layer formed of a second resin material with a higher adhesion to the external terminal than that of the first resin material.

Abstract: A metal case has a bottom part composed of a metal plate, and a side wall part composed of a metal plate that stands from an outer peripheral edge of the bottom part. A boundary part between the bottom part and the side wall part includes a welding portion formed by welding the both parts together. The welding portion is exposed on a surface of the metal case on a lower side in a standing direction of the side wall part. And, a lower end that is a lower end part of the bottom part in the standing direction of the side wall part is located on the lower side in the standing direction than the welding portion is.
