A golf ball is composed of at least a pair of adjacent concentric solid layers or three adjacent concentric solid layers. In the former case, the outer solid layer is composed of a matrix and non-metallic high-hardness grains having hardness higher than that of the matrix which has a Shore D range of 36-40. In the later case, the intermediate solid layer is composed of a matrix and high-hardness grains having hardness higher than that of the matrix. The high-hardness grains have a Shore D hardness in the range of 50-70 and penetrate the corresponding solid layer in normal directions. The golf ball can provide a player with different feels on impact depending on the direction of an external force applied thereto when the golf ball is hit.
