Abstract

In a golf ball having a core, a cover and an intermediate layer therebetween, the ball and a sphere consisting of the core encased by the intermediate layer have surface hardnesses which satisfy a specific relationship, the intermediate layer and the cover have thicknesses which satisfy a specific relationship, and the core has a hardness profile in which the hardnesses at the core center, at positions 5 mm, 10 mm and 15 mm from the core center and at the core surface satisfy specific relationships. This ball, when played by mid- and high-level amateur golfers, achieves a good distance on driver shots, has a soft feel at impact and maintains the spin performance at a high level on approach shots.
