Abstract

A golf ball has a large number of exposed portionson a surface thereof. An average value Hav of heights H of these exposed portionsis not less than 0.5 μm and not greater than 50 μm. The surface of the golf ball has one or more first zones and one or more second zones. An average value Havof the heights H of the exposed portionson these first zones is higher than an average value Havof the heights H of the exposed portionson these second zones. Preferably, the average value Havand the average value Havsatisfy the following mathematical formula.3≤(Hav−Hav)≤50
