NI-CONTAINING PLATING FILM AND METHOD OF MANUFACTURING THE SAME

摘要

A Ni-containing plating film includes a lower plating film and an upper plating film laminated on lower plating film. The lower plating film is formed by plating with no saccharin sodium added to a plating bath, and the upper plating film is formed by plating with saccharin sodium added to a plating bath. In the upper plating film, a NiS layer exists at a position below the film surface.
