| abstract |
The present invention provides a golf ball comprising a core and a cover layer covering the core, wherein the core contains 60% or more of cis-1,4-bonds and uses a rare earth element-based catalyst. Formed from a rubber composition containing a polybutadiene rubber, an organic sulfur compound, an unsaturated carboxylic acid or a metal salt thereof, an inorganic filler and an anti-aging agent, and finished from an initial core load of 10 kgf. The deformation amount and the hardness distribution when the load is applied up to 130 kgf are specified, the cover layer is made of a polyurethane material as a main component, the thickness and surface hardness of the cover layer are specified, and the core and the cover Provided is a solid golf ball having at least one intermediate layer in between, the surface hardness and the total thickness of which are specified. [Effect] According to the present invention, a good deformation is obtained during a driver full shot at a low head speed, the flying performance is excellent, and the approach shot performance is also excellent.
