<p>PROBLEM TO BE SOLVED: To enable to reduce the weight, to prevent self-discharge, to eliminate the need for sealing the lead wire leading-out portion and the like. SOLUTION: A resin frame 1 of PBT is connected to the peripheral part of a first end plate electrode 10, a bipolar electrode 6 and a collector electrode 7 of a second end plate electrode 11, and the perimeter of the laminate is heat welded. A rib 5 protruded from the resin frame is molten by heat and heat welded. A hot melt film of PBT is wound around the perimeter of the laminate, a flat plate of PBT is put on it and they are heated and bonded to each other. A spacer of PBT is interposed in the gap between the concave parts of the resin frame. At the time of lamination, the laminate is pressed by a pressing jig and a clamper. At the time of heat welding, the inside surfaces of the metal plate which are in contact with the perimeter of the laminate are coated with Teflon(R) and a jig for heating equipped with an asbestos plate is used for parts where the metal plate is in contact with both ends of the laminate in the direction of lamination.</p> |
