Abstract:
1. A golf ball comprising a core, a cover, and an intermediate layer between the core and the cover, which ball has a surface with a plurality of non-circular dimples thereon, wherein the cover is harder than the intermediate layer, the ball surface has land areas having a width of from 0.05 to 1.0 mm, the lands having outer surfaces that define an outermost peripheral face of the ball, the non-circular dimples have non-circular inside corners that are curved, and the ball satisfies conditions (I) to (IV) below: (I) (core initial velocity)−(ball initial velocity)≧0; (II) 0.87≦(deflection of intermediate layer-covered sphere)/(core deflection)≦0.97; (III) combined thickness of intermediate layer and cover≦3.0 mm; and (IV) (ball deflection)/(deflection of intermediate layer-covered sphere)≦0.98.
