Abstract
A Ni-containing-surface-treated steel sheet for a can, which is formed by stamping, includes a steel sheet having a first surface which becomes an outer surface of the can after the stamping; a Ni containing layer arranged on the first surface of the steel sheet; and a Ni—W alloy plating layer arranged on the Ni containing layer. The Ni containing layer includes a Fe—Ni diffusion alloy layer; a Ni content included in the Ni containing layer is from 5 g/m2 to 89 g/m2; a thickness of the Ni—W alloy plating layer is from 0.02 μm to 2 μm; and a W concentration in the Ni—W alloy plating layer is from 10% to 65% by mass %.
