摘要： The invention provides a golf ball having a solid core, an intermediate layer encasing the core, and an outermost layer cover of urethane which is softer than the intermediate layer. The outermost layer cover has a surface hardness, expressed in JIS-C hardness units, of at least 76 but not more than 88, and a thickness of at least 0.6 mm but not more than 1.0 mm. Letting A be the deflection of a sphere composed of the core encased by the intermediate layer when compressed under a final load of 1,275 N (130 kg) from an initial load state of 98 N (10 kgf) and B be the deflection of the core when compressed under a final load of 1,275 N (130 kg) from an initial load state of 98 N (10 kgf), the value A/B is at least 0.74 but not more than 0.82. The value expressed as (JIS-C surface hardness of intermediate layer×intermediate layer thickness)−(JIS-C surface hardness of cover×cover thickness) is at least 90 but not more than 120. The golf ball of the invention has a substantially increased travel distance, and can be imparted with a very good spin controllability. Moreover, it also has an excellent durability to cracking under repeated impact and an excellent scuff resistance.
