<p>A wood-type golf club head comprises a club face provided with a high-resilience part whose Young's modulus E is in a range of from 40 to 80 GPa. The head volume is in a range of from 270 to 420 cc. The horizontal inertial moment is in a range of from 3000 to 4500 (g.sq.cm), and the gravity point depth is in a range of from 15 to 25 mm.</p> |
