A partially or entirely exposed metal portion of a club head body is formed with a foundation layer on the surface thereof by means of electroplating, and the foundation layer is covered with a non-electrolytic nickel-boron plating. Moreover, this non-electrolytic nickel-boron plating has a chromate film applied to the surface thereof by using a chromate treatment. The foregoing foundation layer comprises a first electrolytic nickel plating for preventing rust of the head body and a second electrolytic nickel plating for improving the close contact of the non-electrolytic nickel-boron plating with the foundation layer.
