PROBLEM TO BE SOLVED: To provide a Ni-plated steel plate improved in scratch resistance in processing it, corrosion resistance, and a battery characteristic, and also to provide a battery can using it. SOLUTION: The Ni-plated steel plate for a battery can is characterized by having an Fe-Ni diffusion layer on a surface corresponding to an outside surface of the battery can, having a glossy addition agent or a semimat addition agent containing Ni-plated layer on its upper layer, and in that its surface roughness Ra is 0.1-1μm and its Rmax is 1-10μm. In addition, the Ni-plated steel plate for a battery can is characterized by having the Fe-Ni diffusion layer on the surface corresponding to the outside surface of the battery can, having the glossy addition agent or the semimat addition agent containing Ni-plated layer on the upper layer, in that its surface roughness Ra is 0.1-1μm and its Rmax is 1-10μm, and by having an Fe-Ni diffusion layer on a surface corresponding to the inside surface of the battery can, or the Fe-Ni diffusion layer and recrystalized and softened Ni-plated layers on the Fe-Ni diffusion layer.
