摘要： PROBLEM TO BE SOLVED: To provide a golf ball, through a combination of dimples which do not cause a loss of lift in a low-velocity, low-spin rate region of the ball trajectory and a low-spin construction, travels farther and is therefore beneficial for competitive use by both skilled and amateur golfers. SOLUTION: The golf ball G is composed of a core 1, a cover 3 having a plurality of dimples on an outside surface thereof, and an intermediate layer 2 disposed between the core and the cover. The intermediate layer is formed of a highly neutralized resin material, and has a Shore D hardness below 50 and a thickness of at least 1.7 mm but not more than 6.0 mm. The cover and the intermediate layer have a difference in Shore D hardness between the cover Shore D hardness and the intermediate layer Shore D hardness of 13 to 35. The cover and the intermediate layer have a combined thickness greater than 3 mm. The ball as a whole has a deflection, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of at least about 2.0 mm but not more than about 4.0 mm.
