The present invention relates to a solid golf ball having a core and at least one cover, wherein the core contains 60% or more of cis-1,4-bonds and is synthesized using a rare earth element-based catalyst. Polybutadiene is used as the main material, the core has a diameter of 34.7 to 42.0 mm, the deformation amount of the core at a load of 100 kg is 2.5 to 5.0 mm, and the outermost layer cover among the covers Is formed using a thermoplastic resin or thermoplastic elastomer containing organic short fibers as a main material, the outermost layer cover has a Shore D hardness of 55 to 70, a thickness of 0.5 to 2.0 mm, and the entire ball The mass of the golf ball is 40.0 to 44.9 g. [Effect] According to this golf ball, the flying performance and the cracking durability are excellent, and the flying distance can be increased particularly in a player in a low head speed region.
