摘要： A two-piece golf ball includes a core and a cover having a thickness of 1.0 to 3.0 mm. The core is made from a rubber composition containing a main rubber component which mainly contains polybutadiene. The cover is made from a material mainly containing an ionomer resin in which at least one kind of silicone powder selected from a silicone rubber powder, a silicon resin powder, and a composite powder thereof is dispersedly blended. The core has a hardness corresponding to a deflection in a range of 3.3 to 6.0 mm under an applied load of 100 kg. The cover has a Dulometer D hardness in a range of 55 to 70. Dimples of the number of 300 to 550 pieces are formed in the surface of said golf ball in such a manner that a dimple total volume ratio VR, which is a ratio of the total of volumes of dimple spaces under the planes surrounded by edges of the dimples in the surface of said gold ball to the total volume of a virtual ball as a result of assumption that no dimple is formed in the surface of said golf ball, is in a range of 0.85% or less. The two-piece golf ball is excellent in resilience, flight distance characteristic, durability, and feel of hitting.

摘要： In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)null100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.
