<p>PROBLEM TO BE SOLVED: To provide a light golf ball having the excellent flying performance and the excellent hitting feeling. SOLUTION: This golf ball is formed of a core and a cover for covering the core. The cover has 200-600 MPa of bending rigidity factor (F), and the golf ball has 0.50 or more and less than 1.00 of specific gravity at, 3.1-5.0 mm of deformation quantity (D) when a load is changed from the initial load at 98 N to the final load at 1275 N, and a ratio (F/D) of the bending rigidity factor (F) of the cover to the deformation quantity (D) of the ball is set at 50-125.</p> |
