A golf ball 1 includes an A dimple having a diameter of 4.35 mm, a B dimple having a diameter of 3.9 mm, a C dimple having a diameter of 3.4 mm, and a D dimple having a diameter of 3.2 mm. All the dimples have circular plane shapes. A ratio PN of a number Na of the circular dimples having the diameters of 3.9 mm to 4.8 mm to a total number N of the dimples is 75% or more. A volume Va of the circular dimples having the diameters of 3.9 mm to 4.8 mm is 200 mm 3 to 300 mm 3 . A ratio PV of the volume Va to a total volume V of all the dimples is 70% to 95%. A surface area occupation ratio Y of all the dimples is 75% or more.
1. A golf ball including:
(a) at least two types of circular dimples having diameters of 3.9 mm to 4.8 mm; and
(b) a non-circular dimple or a circular dimple having a diameter of less than 3.9 mm,
wherein a ratio PN of a number Na of the circular dimples having the diameters of 3.9 mm to 4.8 mm to a total number N of the dimples is 75% or more,
a volume Va of the circular dimples having the diameters of 3.9 mm to 4.8 mm is 200 mm 3 to 300 mm 3 ,
a ratio PV of the volume Va to a total volume V of all the dimples is 70% to 95%, and
a surface area occupation ratio Y of all the dimples is 75% or more.
2. The golf ball according to claim 1 , wherein a surface area occupation ratio Ya of the circular dimples having the diameters of 3.9 mm to 4.8 mm is 65% or more.
3. The golf ball according to claim 1 , wherein a difference between a diameter of the largest one of the circular dimples having the diameters of 3.9 mm to 4.8 mm and that of the smallest one of the circular dimples having the diameters of 3.9 mm to 4.8 mm is 0.6 mm or less.
