<p>PROBLEM TO BE SOLVED: To provide a sealing member of simple structure having high production efficiency, and high gas barrier properties less likely to transmit gas, e.g., steam or oxygen gas, and to provide a light-weight container for power storage device having a high volume ratio to which the sealing material is welded, and in which intrusion of moisture from the joint to the sealing member, or volatilization of liquid components from the content goods is reduced.SOLUTION: In a sealing member 1 having an inner surface welded to an opening inner surface of a weldable cylinder 51, a sealing wall 2 consisting of a metal foil laminate 21 having a metal foil and a welding layer is welded to the top surface of a frame 3 made of resin, and electrode terminals 4, 4 are fixed airtightly to the sealing wall 2.</p> |
