The present invention provides a golf ball which exhibits a large flying distance and is superior in stability of iron shot and hit feeling. The golf ball comprises a core and a cover for covering the core, the cover comprising two layers of an inner layer cover and an outer layer cover. A stiffness modulus of the inner layer cover is 3,000 to 5,500 kg/cm2 and that of the outer layer cover being 1,000 to 2,500 kg/cm2. A thickness of the inner layer cover is 0.5 to 2.5 mm and that of the outer layer being 0.5 to 2.5 mm. A total thickness of the inner layer cover and the outer layer cover is 1.0 to 4.5 mm. A base resin of the inner layer cover contains 5 to 100% by weight of an ionomer neutralized with a zinc ion.
