Zusammenfassung:	PURPOSE: To provide a battery case by using a material appropriate to improve the formability of the case without deteriorating the resistance of the case to the corrosion of a sealed alkaline soln., to allow the inner face of the case to maintain alkali corrosion resistance and to improve the electric-contact performance of its outer face. CONSTITUTION: The inner face of the case is plated with nickel at 5-40g/m , and the outer face is plated with tin at 2.8-17g/m . Besides, the inner face is plated with nickel at 5-40g/m , the outer face is plated with tin at 2.8-17g/m , and a part of the nickel plating layer forms an tin-nickel alloy layer.
