Provides golf ball with large distance, excellent approach performance and durability. A golf ball according to the present invention is a golf ball having a spherical core composed of a spherical inner layer core and an outer layer core, an intermediate layer provided on the outer side of the spherical core, and a cover provided on the outer side of the intermediate layer, ) And hardness difference (Hs1-Ho) of surface hardness (Hs1) were 5 or less in JIS-C hardness and the thickness of outer core was 9 points in 12.5% interval in radial direction of spherical core. Is plotted against the distance (%) from the boundary point between the outer layer core and the inner layer core, R 2 of the linear approximation curve obtained by the least squares method is 0.95 or more, and the slab hardness of the intermediate layer is larger than the slab hardness Big. |
