    Abstract: A golf ball having a plurality of different kinds of dimples formed on a spherical surface thereof is disclosed. In one embodiment, a plurality of four different kinds of dimples is formed on the spherical surface of the golf ball. The differences between the kinds of dimples can be a difference in diameter, in depth, or a combination of diameter and depth. The ratio of the product of the diameter and the depth of the largest dimple, to the product of the diameter and depth of the smallest dimple, is in the range of 1.5 to 2.0. Smooth portions are formed on the remainder of the spherical surface to such a size that a dimple having an area larger than an average area calculated from the respective areas of each kind of dimple constituting the plurality of different kinds cannot be formed. The total number of dimples ranges from 300 to 560, and there is a maximum of one great circle zone not traversing a part of any dimple.
