PROBLEM TO BE SOLVED: To provide a golf ball capable of generating behavior of a hit corresponding to a purpose, for each club such as a driver or a wedge.SOLUTION: A golf ball includes: a spherical core 1; an intermediate body 5 which covers the core 1 and is composed of at least one layer; and a cover 7 which covers the intermediate body 5. In the intermediate body 5, JIS-C hardness of a surface of a layer at least on the outermost side is greater than JIS-C hardness of a surface of the core 1 by at least 10, specific gravity of the core 1 is greater than 1.5, and specific gravity of the layer at least on the outermost side in the intermediate body 5 is smaller than 1.0. |
