A battery case excellent in glossiness of appearance and working efficiency and a surface-plated steel plate which can be used preferably to manufacture the battery case. The battery case is produced by deep-drawing, DI-forming, DTR-forming a surface-treated steel plate having glossy nickel or glossy nickel-cobalt alloy plating on the outermost layer corresponding to the external face of a battery case of a plated original plate consisting of a steel plate. The glossy nickel plating or glossy nickel-cobalt alloy plating layer on the outermost layer has a high glossiness, and therefore the appearance is excellent. The runnability of a formed battery case is high as well as the working efficiency.
