摘要： The present invention provides a multi-piece solid golf ball having a core obtained by molding under heat a specific rubber composition and having a cover of at least three layers which encases the core. By optimizing the deflection of the core under a specific load, optimizing the hardness at the center of the core and the hardnesses of the innermost cover layer, outermost cover layer and intermediate cover layer, setting the combined thickness of the cover layers to at least a specific value, and forming the innermost cover layer of a highly neutralized ionomer resin composition, a sufficient reduction in the spin rate of the ball on shots taken with a driver can be achieved, enabling the distance traveled by the ball to be increased.

摘要： The invention provides a method of manufacturing golf balls composed of a core and one or more cover layer which encloses the core, at least one cover layer being a thin layer having a thickness of 1.0 mm or less. The thin layer is formed to a desired thickness on a surface of a core or spherical body by holding within a mold cavity the core or a spherical body composed of the core enclosed by a cover layer and injecting a synthetic resin material into a space defined by a surface of the core or spherical body and an inner face of the mold cavity so as to form a cover layer on the surface of the core or spherical body, then grinding the resulting cover layer to a thickness of at least 0.1 mm with a specific type of grinder. Golf balls obtained in this way can be provided with a good sphericity even when the cover is formed to a very small thickness.
