Abstract
A metallic golf club head of which the center of gravity is kept a large distance off from a face to enlarge a sweet area, which also enables players to hit balls more easily upward. In one embodiment, a back crust of the head body made of pure titanium or titanium alloy is formed with a window aperture, into which is secured a weight made of beryllium copper alloy. In another embodiment, a weight is secured onto a sole by vises with a large specific gravity. According to the invention, the center of gravity of head body is capable of being positioned as backward and low as possible, so that the distance between the face and the center of gravity can be elongated, making it easier to hit balls upward.
