Patent ID: 10080929

Abstract:
A golf ball 2 includes a core 4, one or more mid layers 6, a cover 8, and dimples 10. A central hardness Ho and a surface hardness Hs of the core 4, a hardness Hm(min) of a layer having a lowest hardness among the mid layers 6, and a hardness Hc of the cover 8 satisfy the following mathematical formulas (1) to (4). Hs−Ho>15  (1)Hc−Hm(min)>20  (2)−10<Hm(min)−Ho<15  (3)5<Hc−Hs<20  (4) An occupation ratio So and a ratio Rs of a number of the dimples 10 each having a diameter of from 9.60% to 10.37% of a diameter of the golf ball 2, relative to a total number of the dimples 10, satisfy the following mathematical formula (5). Rs≥−2.5*So+273  (5).
