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.
