Abstract (en)
An object is to provide a method for forming a superior corrosion-resistant plating layer by sealing penetrating pinholes formed in an electroless plating layer. There are provided a first plating step of performing electroless Ni-P plating on a base material (1); an etching step of etching a surface of a first plating layer (3) formed by the first plating step; and a second plating step of performing electroless Ni-P plating to form a second plating layer (5) on the first plating layer (3) processed by the etching step.
