摘要: Golf ball 1 has numerous dimples 4 on its surface. The dimple 4 comprises an inclined face 6, a circular flat face 7, an annular groove 8 and a round flat face 9. Surface area s1 is calculated by summing up the surface area of the inclined face 6, the surface area of the circular flat face 7, the surface area of the annular groove 8 and the surface area of the round flat face 9. The ratio (S1/S2) between a summation S1 of surface areas s1 of all the dimples, and a summation S2 of the areas s2 of the regions cut away by the dimples on the phantom spherical face is equal to or greater than 1.02. Total value (Cb+Cc) of the amount of compressive deformation Cb of the golf ball 1 and the amount of compressive deformation Cc of the core is equal to or greater than 7.0 mm.
