A golf ball having a multiplicity of dimples in its surface is adjusted to a weight of 40 to 45 grams and a diameter of 43 to 47 mm. The dimples occupy at least 60% of the ball surface and satisfy 0.35</=V0</=0.60 wherein V0 is the volume of the dimple space below a circular plane circumscribed by a dimple edge, divided by the volume of a cylinder whose bottom is the circular plane and whose height is the maximum depth of the dimple from the bottom. The ball is improved in flying performance in that it offers an adequate trajectory and an increased flying distance when hit by an ordinary golfer with a head speed of about 40 m/sec. with a driver or long iron. Hitting feel is also improved.
