PURPOSE:To produce an Ni plated steel sheet excellent in corrosion resistance and plating adhesion by applying Ni plating to the surface of a cold rolled steel sheet via Ni or Ni-Co striking and then forming the Ni plating into Fe-Ni diffused layer of specific quality by means of heat treatment. CONSTITUTION:The surface of a steel sheet, such as cold rolled sheet of aluminum killed steel, is degreased with alkali solution, etc., water-washed, and pickled, by which the surface is cleaned. After striking with Ni or Ni-Co alloy is applied to one side or both sides of the steel sheet, Ni plating is applied to the resulting striking layer to 1-5mum thickness. Successively, heat treatment is applied to this Ni plated steel sheet to diffuse the Fe in the steel sheet into the Ni plating layer, by which an Fe-Ni alloy plating layer is formed. At this time Fe/Ni in the outermost surface of the Fe-Ni plating layer is regulated to
