Abstract
Disclosed is a golf club head including a faceplate portion and a main body constituting a remaining part of the golf club head. A plurality of linear protrusions formed parallel to one another on the rear surface (opposing to the front striking surface) of the faceplate portion. The linear protrusions have different lengths and are arranged in an elliptical pattern or a diamond pattern covering the vertical projection of the center-of-gravity of the golf club head on the rear surface of the faceplate portion.
