<p>PROBLEM TO BE SOLVED: To provide a solid golf ball having a core easy to manufacture and excellent in recycling property, and having flying performance equal to or higher than in the past. SOLUTION: In a solid golf ball formed of a core 1 and a cover 2 covering the core 1, the core 1 is formed of a molded body of a thermoplastic elastomer composite having a bending elasticity of 400-3000kgf/cm<2> obtained by dispersing diene rubber in a thermoplastic resin, and dynamically cross-linking the diene rubber by a cross-linking agent to disperse a of the 10μm or less in the thermoplastic resin. Further, the ball cross-linked diene rubber grain having an average grain size compression (the deformation quantity from the state where an initial load of 10kgf is added to tire ball to tire state where a final load of 130kgf is added thereto) is set to 2.2-4.5mm.</p> |
