摘要: A golf ball 2 includes a core 4, a mid layer 6, and a cover 8. A hardness H75 at a point to which a distance from a central point of the core 4 is 75% of a radius of the core 4 is greater than a hardness H0 at the central point of the core 4. A difference D1=(H75−H0) is not less than 10.0 and not greater than 27.0 in Shore C hardness. A hardness Hs at a surface of the core 4 is greater than the hardness H75. A difference D2=(Hs−H75) is not less than 0 and not greater than 6.5 in Shore C hardness. The hardness H75 is less than a Shore C hardness HmC of the mid layer 6. A Shore D hardness HmD of the mid layer 6 is greater than a Shore D hardness Hc of the cover 8.
