Patent ID: 7192366

Claim:
A three-piece solid golf ball comprising a center, an intermediate layer formed on the center and a cover covering the intermediate layer, wherein the center has a deformation amount of 3.5 to 5.5 mm, when applying from an initial load of 98 N to a final load of 1275 N, a hardness difference in Shore D hardness (H S −H C ) between a surface hardness (H S ) and a central point hardness (H C ) of 12 to 40, and the surface hardness (H S ) of 36 to 50, the intermediate layer has a base resin formed from a thermoplastic resin having a weight ratio of thermoplastic elastomer to ionomer resin of 20/80 to 70/30, and the intermedidate layer has a hardness (H M ) in Shore D hardness of 36 to 50, ther cover has a base resin fsormed from a thermoplastic resin mainly comprising an ionomer resin, and the cover has a hardness (H L ) in Shore D hardness of 58 to 69, and the hardness difference (H S −H M ) between the surface hardness of the center (H S ) and the hardness of the intermediate layer (H M ) is within the range of 0.5 to 15, and the hardness difference (H L −H M ) between the hardness of the cover (H L ) and the hardness of the intermediate layer (H M ) is within the range of 10 to 28.
