Abstract
A golf club head made of a hollow metal comprising a face and a body, wherein at least the face is made of a rapidly solidified Al-based alloy having a high strength, high elasticity and light weight. This golf club head makes it possible to stroke a ball without elastic deformation of its face and also to fly the ball farther with the initial speed thereof maintained, by using the Al-based alloy at least in the face. In addition, the use of the Al-based alloy makes it possible to form a large head and a long shaft so that balls can be stroked to fly over a long carry in an accurate direction.
