Abstract

The present invention relates to a golf club head, on the internal surface of the striking surface of the head portion of the golf club head is formed an annular wall, an inner board made of lightweight material having strong strength is disposed between the annular wall and the striking surface, thus shifting the center of gravity of the golf club head backwards while improving the flexibility of the balance weight of the golf club head. As a result, the stability of the golf club, the flying stability of the golf ball and the distance that the golf ball travels can be optimized.
