[Problem] To provide a golf ball that achieves both a flight distance during a shot of a driver, a long iron, a middle iron, etc. and a controllability during an approach shot, such as a short iron, and is excellent in abrasion resistance of a cover. . A golf ball 2 cover composition includes, as a resin component, a thermoplastic polyurethane, a urethane prepolymer having at least two isocyanate groups or a polyisocyanate having at least three isocyanate groups, and an isocyanate group. The cover composition is formed of a polyisocyanate mixture dispersed in a thermoplastic resin that does not substantially react. The slab hardness of the cover composition is 60 or less in Shore D hardness, and the core has a surface hardness Hs and a center hardness Ho. Difference in hardness (Hs-Ho) is 15 to 50 in Shore D hardness. [Selection] Figure 1 |
