<p>PROBLEM TO BE SOLVED: To provide a golf ball which can be used favorably especially in a city driving range built in a limited space, as the feeling of impaction is good, the trajectory can be made sufficiently low, and the decline in flight distance can be reduced. SOLUTION: In a golf ball with many dimples formed on its surface, dimples satisfying Dm /Dp =10 to 15 account for 80% or more of the total number of dimples when the weight is 46.5 to 49.0g and the amount of deformation of the ball at constant load of 100kg is 2.5 to 4.0mm, wherein Dm is the diameter of each dimple and Dp is the depth.</p> |
