<p>PROBLEM TO BE SOLVED: To facilitate the movement of the center of gravity of a head, and to increase the degree of design freedom for the position of the center of gravity. SOLUTION: In a wood club head of a hollow thin thickness shell body whose volume is 230 cc or more, the head rear part 1B corresponding to 20 to 40% of the head volume is made with a material of soft and high specific gravity thicker in thickness than the remainder head front part 1A, and the back side of the head rear part 1B or the part ranging from the back side to the sole part 6 is made so that at least one platelike weight 8 is fitted.</p> |
