Golf ball 1 includes a core 2 formed by crosslinking a rubber composition and a cover 3 comprising a resin composition. The cover 3 has a two-layered structure including an outer cover layer 4 and an inner cover layer 5. A number of dimples 6 are formed on the surface of the cover 3. The outer cover layer 4 has a Shore D hardness of from 58 to 72. The golf ball 1 has an amount of compressive deformation of from 2.5 mm to 4.0 mm when measured with applying an initial load of 10 kgf to a final load of 130 kgf. Percentage of the number of dimples having a contour length of greater than or equal to 11.6 mm occupied in total number of dimples is greater than or equal to 50%.
