Collector terminals are connected to a positive electrode and to a negative electrode of the electricity generating element. The collector terminal are airtightly crimped in the secondary sealing area of the laminated sheathing. Also, the collector terminals extend outwardly of the laminated sheathing. The primary sealing part of the laminated sheathing is located over a surface of the electricity generating element.
