Abstract
A golf ball has a large number of dimples (A to D) on a surface thereof. A surface area occupation ratio Y of the dimples is 0.80 to 0.90. A total volume V of the dimples is 300 mmto 700 mm. A mean volume Va to be a value obtained by dividing the total volume V by a total number N of the dimples is 1.30 mmor more. A mean curvature R to be a mean value of a curvature r in the sectional shape of the dimple is 16 mm or more. A mean occupation ratio y to be a value obtained by dividing the surface area occupation ratio Y by the total number N of the dimples is 0.0022 or more. A sum X of a contour length x of the dimple and the surface area occupation ratio Y satisfy a relationship indicated by an expression (I):.  (I)
