Abstract
A Ni-plated steel sheet according to one aspect of the present invention includes a base steel sheet and a Ni plating layer provided on a surface of the base steel sheet, the Ni plating layer has a Ni—Fe alloy layer formed on a surface of the base steel sheet, and a ratio of a Zn content to a Ni content in the Ni plating layer is 0.0005% to 0.10%. A manufacturing method of the Ni-plated steel sheet according to one aspect of the present invention has electroplating a base steel sheet using a Ni plating bath in which [Zn]/[Ni] is set to 0.0005% to 0.10% to obtain a material Ni-plated steel sheet, and annealing the material Ni-plated steel sheet.
