Golf ball
Abstract:
A golf ball 2 has, on a surface thereof, a plurality of types of dimples 8 having different diameters from each other. A standard deviation Vσ of the volumes of all the dimples 8 is equal to or less than 0.095 mm3. The ratio (Vσ/Dσ) of the standard deviation Vσ to a standard deviation Dσ of the diameters of all the dimples 8 is equal to or less than 0.35. Preferably, the shape of each dimple 8 is a portion of a spherical surface. The standard deviation Vσ is preferably equal to or less than 0.087 mm3. The ratio (Vσ/Dσ) is preferably equal to or less than 0.29.
