Abstract
In a golf ball having on its surface a multiplicity of dimples, the dimples include a majority of large dimples with a diameter of 3.0 to 4.2 mm and account for at least 65% of the entire ball surface area. The large dimples have a depth of 0.1-0.35 mm, an edge angle of up to 30°, and a radius of curvature at the edge of 1-50 mm. Not only excellent flight performance is achieved, but the ball can be smoothly released from a mold at the end of molding.
