<p><P>PROBLEM TO BE SOLVED: To provide a multi-piece solid golf ball which can sufficiently reduce a spin rate on shots taken with a driver and can increase a carry. <P>SOLUTION: The multi-piece solid golf ball (G) has a core (1) obtained by molding under heat a specific rubber composition and at least three cover layers (2), (3) and (4) which are made of a thermoplastic resin material and cover the core. The deflection of the core under a specific load and the hardness at the center of the core and the hardnesses of the innermost cover layer, outermost cover layer and intermediate cover layer are optimized, the combined thickness of the cover layers is set to at least a specific value, and the innermost cover layer is formed of a highly neutralized ionomer resin composition further. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
