Abstract
A Ni-plated steel sheet according to the present invention includes a steel sheet, a first Ni-plated layer which is formed at least on a one-sided surface of the steel sheet and contains Ni, and a second Ni-plated layer which is formed on the first Ni-plated layer and contains Ni. An average central-line roughness Ra at an interface between the first Ni-plated layer and the second Ni-plated layer is less than 0.1 μm, an average central-line roughness Ra of a surface of the second Ni-plated layer is 0.1 μm to 100 μm, and a coating amount of Ni in the entirety of the first Ni-plated layer and the second Ni-plated layer is 20 mg/mto 2500 mg/mper one-sided surface in terms of metal Ni.
