Abstract:
To provide a golf ball that improves flight performance.SOLUTION: A golf ball according to the present invention comprises a spherical core, at least one cover member for covering the core, and a coating layer for coating the cover member constituting an outermost layer. The cover member constituting the outermost layer is formed with a plurality of dimples. Roughness is formed on a surface of the coating layer so that a relationship between a drag coefficient CD1 and a lift coefficient CL1 when the ball is hit on condition of Reynolds number of 1.771×10and a spin amount of 2280 rpm can satisfy the inequality: CD1×CL1<0.0370.SELECTED DRAWING: Figure 1
