摘要： The present invention provides a golf club head comprising, a face, a plurality of score line grooves formed in the face, traces formed in the face by milling; and a pair of side surfaces of the score line groove including a first surface that is contiguous with the face and a second surface that is contiguous with the first surface in the depth direction of the score line groove. A first angle that is formed by each first surface of the pair of side surfaces is larger than a second angle that is formed by each second surface of the pair of surfaces. The face in which the traces are formed has the arithmetic mean deviation of the profile (Ra) of not less than 4.00 μm.
