摘要： The present invention provides a solid golf ball which has an improved flying distance, controllability and shot feeling. The solid golf ball has a core and a cover. The core has a hardness of 55 to 75 at a center thereof and a hardness on a surface thereof that is greater than the hardness at the center by 10 or more. The cover has a hardness satisfying the following expressions (1) and (2): (hardness of the cover)−(hardness at the center of the core)≦17 (1), (hardness of the cover)−(hardness on the surface of the core)≦5 (2). The hardness being defined in terms of JIS-C scale hardness meter.
