Abstract

PROBLEM TO BE SOLVED: To improve range performance by effectively reducing the primary peculiar vibrations of a face and approximating them to the primary peculiar vibrations of a golf ball by providing a loop-shaped groove part on the inner surface of a face wall part so as to surround the central part of this inner surface. SOLUTION: Concerning the woody golf club head in hollow structure formed from a face wall part 1 forming the face, crown part, side part, sole part and neck part, on an inner surface 6 of the face wall part 1, a loop-shaped groove part 7 is provided so as to surround the central part of the inner surface 6. With such a golf club head, the number of primary peculiar vibrations of the face wall part 1 can be remarkably decreased and the number of primary peculiar vibrations of the face wall part 1 can be a value closer to the number of primary peculiar vibrations of the ball while making almost similar to the conventional head the outer form, size and total weight of this head. Thus, range performance can be improved.
