Abstract:
A Ni-plated steel sheet according to an aspect of the present invention includes: a base steel sheet; an Fe—Ni diffusion alloy region disposed on the base steel sheet; and a Ni plating region disposed on the Fe—Ni diffusion alloy region, in which an average equivalent circle diameter of crystal grains made of Ni (fcc) in the Ni plating region measured in a cross section perpendicular to a rolled surface of the base steel sheet is 0.2 to 4.0 μm.
