が好ましい。Anode and cathode terminals of lead or lead alloy parts2. A cap 1 is manufactured by insert molding Z and molding a cylindrical exhaust part 3 at the same time. The ears 7.7 of the electrode plate group 6 are welded and joined to the terminals 2.2 protruding downward from the cap l. The bag body 8 that houses the electrode plate group 6 is made by sealing the back of a synthetic resin film or sheet and then sealing one end 9 to form an envelope shape. The aforementioned electrode plate group 6 is stored in the bag 8 and inserted until the opening of the bag 8 reaches the stepped portion 12 of the cap l. After positioning, pressure is applied from the surface of the film or sheet by thermal force generated by heating with a heater to melt and thermally weld the resin 114 on the inner surface of the film or sheet to the surface of the cap 1. Therefore, the welding surface of the bag 8 is preferably made of the same material as the cap 1, and the film or sheet surface is preferably made of CPP, the cap is made of polypropylene resin, or the film or sheet surface is preferably made of LDPB, and the cap is made of polyethylene resin.

取り付けられている。Weld defects tend to occur at some corners of the cap. To prevent this defect, reliability can be improved by first welding some of the four corners of the cap and then welding the flat portion. The cap 1 is provided with a cylindrical exhaust part 3, and a rubber safety valve 5 is attached to this part, and when the internal pressure of the storage battery increases, the safety valve 5 opens to release the pressure. Reference numeral 4 denotes a lid that presses and holds the safety valve 5, and is attached to the cap 1 so as to cover the recessed portion in which the safety valve 5 is accommodated.
