みであるため、剥離や亀裂が生じ易く信頼性に欠ける。As described above, according to the conventional structure and method, the portion of the electrode lead 53a of the metal foil on which the active material 54 is not applied is directly fixed to the reinforcing plate 52 by resistance welding to be integrated. In general, the metal foil on which the electrode leads 53 are formed is often very thin and has a thickness of about 10 μm. Therefore, the foil is melted during resistance welding and is easily attached to the welding electrode. Therefore, there are the following problems. Welding electrode maintenance increases. The range of welding setting conditions is narrow, making setting difficult. Productivity decreases due to the cause of. Workability is poor because the metal foils (the portions of the electrode leads 53a) are not bound together. Since only the foil is around the weld nugget, peeling or cracking is likely to occur and reliability is poor.
