<p><P>PROBLEM TO BE SOLVED: To provide a golf ball 2 which is excellent in flight performance of a shot by a driver and control performance of a shot by short irons. <P>SOLUTION: The golf ball 2 includes a spherical core 4, an intermediate layer 6 located outside the core 4, and a cover 8 located outside the intermediate layer 6. The core 4 includes a spherical center 10 and a surrounding layer 12 located outside the center 10. The intermediate layer 6 is made of a resin composition. The resin composition contains a highly elastic polyamide resin having a flexural modulus of 700 MPa or higher and 5,000 MPa or lower, a metal-neutralized product of ethylene-(meth)acrylic acid copolymer, and a resin having a polar functional group. The cover 8 shows the shore D hardness H7 of 50 or lower. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
