を形成する。The golf club head according to the present invention is manufactured by the following method. The face member 5 according to the present embodiment uses the beryllium-nickel alloy to form a plate having the outer shape shown in FIG. 3 by a conventionally used method such as press working, and forms a plate on the back surface of the plate. Rim 6
The thin part 8 having a smaller thickness is formed by forging or N
It is formed by C cutting. When the thin portion is formed by forging, the plate-shaped body is fixed to a predetermined jig with the back surface facing upward, and forged by a press die corresponding to the shape of the thin portion from above. In the case where the thin portion is formed by NC cutting, a numerically controlled cutting lathe in which a back surface side of the plate-like body is fixed to a predetermined jig with the upper surface facing upward, and a movable area is set in the shape of the predetermined thin portion. Then, the thin portion is formed.
