A golf ball which includes a surface as an imaginary spherical surface, and dimples (2) arranged on the imaginary spherical surface in such a manner that when the ratio of the sum total of flat faces for the areas surrounded by outer edges of the respective dimples (2), to the surface area of the golf ball imaginary spherical surface is represented by y, the total number of dimples (2) and the sum total of the dimple areas are arranged so that the value of y is in a range of +/-0.04 of a value Y which is the optimum value of y as derived from the relation with respect to the dimple total number X by the equation:- Y=0.046.X<1/2>-0.172. <IMAGE> |
