摘要： A golf ball includes a solid core, an intermediate layer, and a cover in a surface of which a plurality of dimples are formed. The solid core has a center JIS-C hardness of 50-70 and a surface JIS-C hardness of 60-80, and has a diameter of 35-40 mm. The intermediate layer is made from a material mainly containing an ionomer resin, and has a JIS-C hardness of 70-85 and a thickness of 0.5-2 mm. The cover is made from a material mainly containing an ionomer resin, and has a JIS-C hardness of 85 or more and a thickness of 0.5-2 mm. A difference in JIS-C hardness between the intermediate layer and the surface of the solid core is in a range of 15 or less. A different in JIS-C hardness between the cover and the intermediate layer is in a range of 10 or more. The hardnesses of the solid core, the intermediate layer, and the cover satisfy a relationship of (hardness gradient from intermediate layer to cover)/(hardness gradient from core center to intermediate layer)≧6. The dimples are arranged such that there is no great circle line not crossing any one of the dimples. The golf ball can exhibit a very soft hitting feel, an excellent durability, a low spin rate and a high hitting angle, and an increased carry due to a high resilience.

摘要： In a multi-piece golf ball comprising a core, an intermediate layer, and a cover, the ratio of A/B is set to be 1.10/1 or greater wherein A is a deflection under a load of 100 kg of the core and B is a deflection under a load of 100 kg of a sphere having the core enclosed with the intermediate layer, and the coefficient of restitution of the ball at a firing velocity of 25 m/s minus the coefficient of restitution of the ball at a firing velocity of 50 m/s is less than 0.100. The ball shows performance less dependent on a head speed, a distance exactly corresponding to a particular number of club used, and improved flight performance at a high head speed.

The core has a deflection of 3.5-5.5 mm when under a load of 100 kg, and has a JIS-C hardness at its surface of at least 70 and a JIS-C hardness at its center which is at least 10 units lower than the hardness at the core surface. The ball, when hit with a driver at a head speed of 50 m/s, has an effective contact area A and an apparent contact area B with the club face such that the ratio A/B is from 0.40 to 0.60. The ball has a soft feel, fully adequate spin characteristics, and excellent control on approach shots, and is well suited for use by golfers having a head speed of less than about 40 m/s.

摘要： A golf ball includes a core, two or more intermediate layers, and a cover. In the golf ball, convex ribs are formed on the outer surface of the innermost intermediate layer (surrounding layer) covering the core such that the ribs intrude into an intermediate layer adjacent to the surrounding layer. Further, the hardness of the surrounding layer is made greater than those of the core and the intermediate layer adjacent to the surrounding layer.
