A method for manufacturing a golf club head having a hollow structure composed of a main body-member and a metal face member welded thereto, comprises the steps of: (a) preparing a rolled material having a constant thickness; (b) cutting out a face member part or blank from the rolled material; (c) making the face member by forming the turnback through press working on the face member part; and (d) reducing the thickness of a corresponding-to-turnback region by machining prior to the step (c), wherein the corresponding-to-turnback region is a region of the cutout face member part corresponding to the turnback, or a region of the rolled material corresponding to the turnback. |
