Abstract
In a golf ball having a core and a cover of one or more layers, letting the core diameter be D (mm), the cover thickness be T (mm) and the core and ball deflections when compressed under a final load of 1,275 N (130 kgf) from an initial load state of 98 N (10 kgf) be 5 (mm) and B (mm), the following conditions are satisfied: (1) 30≧D/T≧24, (2) 3.9≧E/T≧3.0, and (3) 1.18≧E/B≧1.09. This golf ball provides an excellent flight, performance and a soft feel at impact when used by golfers whose head speed is not very fast, such as senior golfers and women golfers. The ball also has a high durability to cracking on repeated impact.
