The golf ballhas a plurality of dimpleson a surface thereof. A value V calculated by the following mathematical formula is equal to or less than 290.In the mathematical formula, N represents a total number of the dimples, So represents a ratio of a total area of all the dimplesrelative to a surface area of a phantom sphere of the golf ball, and Bb represents an average (mm) of thicknesses B of the coverimmediately below deepest points of the dimples
