ABSTRACT:
A golf club head having a high strength and a larger sweet area, which is provided by using light metal such as titanium or titanium alloy. A face crust, an upper crust, a sole and side-peripheral crust are combined together with a neck to form a golf club head. Each crust is formed by forging metal plate of titanium or titanium alloy. The thickness of each crust is adjusted to suitably enlarge a volume of a hollow interior of a golf club head. The hollow interior has a volume of 240 cc or above. According to the invention, the hollow interior of the head is suitably enlarged, ensuring the structural strength of a golf club head so that the distance L between the center of gravity G of the head and the face thereof may be elongated, whereby the sweet area can be enlarged.
