Summary:PROBLEM TO BE SOLVED: To provide a golf ball capable of obtaining a longer carry. SOLUTION: The golf ball includes a spherical core 1, an intermediate layer 10 covering the core 1 and a cover 7 covering the intermediate layer 10. The core 1 includes a support part 11 constituted by at least one support piece which extends outward in the radial direction from the center side and is in contact with the intermediate layer 10, and an outer core layer 12 which is in contact with the support part 11, forms a spherical shape and is in contact with the intermediate layer 10 in an area larger than the support part 11. The elastic modulus of the outer core layer 12 is smaller than the elastic moduli of the support part 11 and the intermediate layer 10. COPYRIGHT: (C)2009,JPO&INPIT
