PROBLEM TO BE SOLVED: To provide a plated steel plate for battery case having no possibility of separation and cracks of the plate layer at forming process into battery case, superior in corrosion resistance to alkali solution, and having excellent battery characteristics, and a battery case using the plated steel plate for battery case, and a battery using the battery case. SOLUTION: A plated steel plate in which bismuth plating is applied on the side of battery case inner face of steel plate and cobalt plating is applied on top of it, or a plated steel plate in which nickel plating is applied, and bismuth plating is applied on top of it, and further, cobalt plating is applied on the top, or a plated steel plate in which nickel plating is applied, then, heat treatment is applied, and bismuth plating is applied on top of it, and further, cobalt plating is applied on the top is formed to make the plated steel plate for battery case, and by forming process into battery case, it is applied to a battery.
