る方法が採用されていた。Prior Art A conventional spiral electrode body is manufactured by winding up a separator 1, an anode plate 2, and a cathode plate 3 in a spiral shape around a winding shaft 4, as shown in Figure @2. However, since the seed plate is harder and more difficult to bend than the separator 1, the tip of the electrode plate has the disadvantage that it is easy to cause separation failure. In order to solve this problem, as shown in Fig. 3, a pair of separators 1
There is a method in which a pair of separators 1 are overlapped and welded using a welding jig 5 to form a double structure, or as shown in FIG. ), a method has been adopted in which short circuits due to damage to the separator 1 are prevented by sandwiching the separator 1 with a clamping tool 6 to form a double structure.
