<P>PROBLEM TO BE SOLVED: To provide a golf ball 2 excellent in flying performance at a middle iron shot and control performance at a short iron shot. <P>SOLUTION: The golf ball 2 includes a core 4, an intermediate layer 6, and a cover 8. The core 4 includes a center 10 and an enveloping layer 12. The ratio of the volume Ve of the core 4 to the volume of a phantom sphere of the golf ball 2 is≥ 76% or more. The ratio (Co/Ce) of the amount Co of compressive deformation of the center 10 to the amount Ce of compressive deformation of the core 4 is in the range of 2.0-3.0. The ratio (Vo/Ve) of the volume Vo of the center 10 to the volume Ve of the core 4 is in the range of 0.01-0.13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
