A golf ball 2 has, on a surface thereof, a plurality of types of dimples 8 having different diameters from each other. The standard deviation of the curvature radii of cross sections of all the dimples 8 is 0.90 mm or less. The average of the curvature radii of the cross sections of all the dimples 8 is greater than 40% but 50% or less of the diameter of the golf ball 2. The sum of the volumes of all the dimples 8 is 280 mm3 or greater but 350 mm3 or less. The average of the diameters of all the dimples 8 is 3.9 mm or greater but 4.5 mm or less. The ratio of the sum of the areas of all the dimples 8 to the surface area of a phantom sphere of the golf ball 2 is 75% or greater but 95% or less.
