Abstract
A golf ball has a large number of dimples (A dimples and B dimples) on a surface thereof. X and Y satisfy a relationship of an equation (I): X≦3882·Y+1495 (I), X representing a total of dimple contour lengths x and Y representing a surface area occupation ratio of the dimples. The surface area occupation ratio Y of the golf ball is 0.70 to 0.90. The number of dimples having the dimple contour length x of 10.5 mm or more is 91% of a total number of the dimples or more.
