PROBLEM TO BE SOLVED: To provide a plated steel plate for a battery capable of obtaining sufficient close adhering properties of battery container inner face and a cathode mixture, and discharging properties with high efficiency. SOLUTION: The plated steel plate for a battery is formed by applying a plating of nickel-based alloy such as nickel-phosphor alloy, nickel-boron alloy, or nickel-tungsten alloy, after applying nickel plating on inner face of the battery container, or by applying a heat treatment after applying one of the nickel-based alloy plating. Thereafter, a hydrated oxide of cobalt on the nickel-based alloy plating layer is formed or on an alloy layer is formed by thermal diffusion of iron and the nickel-based alloy by using electrolysis method and is set as plated steel plate for the battery container, and this is applied to the battery by shaping work on it.
