<p>PROBLEM TO BE SOLVED: To improve distance, controllability and a feeling associated with the hitting of a ball by specifying the hardness of a cover for a solid golf ball having a core and a cover covering the core and the ratio of compression values of the solid golf ball and the core. SOLUTION: The solid golf ball has a core and a cover covering the core. In a such case, the cover's Shore D hardness is set at less than 63, preferably between 45 and 62. The radio of the compression value of the solid golf ball of 2.54 mm to that of the core of 2.54 mm is kept at 1.3 to 1.6. The thickness of the cover is not specified. However, it is set at 2.0 to 2.4 mm. The cover material is formed of a thermoplastic elastomer composition containing an ionomer resin and the rubber component of a diene rubber, etc., excelling in impact resilience and durability despite low shore D hardness.</p> |
