Abstract
In a golf ball according to the present invention, dimples formed on the surface thereof have the same diameter and are classified into first group dimples and second group dimples, and optionally different kinds of dimples within each group, the dimples of one kind differing in depth from the dimples of another kind within that group, each of the first group dimples having a depth substantially the same which is greater than the depth of each of the second group dimples which is also substantially the same for all the second group dimples. The depth of the first group dimple is from 130% to 280% of that of the second group dimple. Further, the number of the first group dimples is from 20% to 80% of the total number of the dimples.
