Abstract
In a sealed power storage device, a device case includes a resin case body with an opening and a resin lid closing the opening. The resin lid is made of electrical insulation resin. A metal terminal member is extended from inside to outside of the device case, penetrating through the resin lid. The resin lid is hermetically molded together with the metal terminal member so that the resin lid is directly joined to the outer peripheral surface of the metal terminal member without interposing another member between the resin lid and the metal terminal member.
