<p>PROBLEM TO BE SOLVED: To provide a golf club head capable of improving a carry by lowering the center of gravity even in a deep face, reducing the spin of a ball, and increasing the hitting angle without hindering the appearance of the golf club head and without lowering the strength thereof. SOLUTION: In this golf club head having the hollow structure, a crown part 2 is provided with an opening 2a, and a plate member 5 made of a material having a specific strength >=294 N/mm<2> is installed in the opening 2a. As a result, the golf club head having a volume >=350 cc, the center-of-gravity retreat quantity GR from a shaft axis S >=15 mm, a center-of-gravity position ratio GH/FH obtained from the maximum height FH of a face surface 1a and the center-of-gravity height GH on the face surface 1a <=0.61.</p> |
