The application provides that flying distance is large, the golf of Approach performance and excellent in te pins of durability.Golf of the present invention, possess golf main body and the film being arranged on described golf body surfaces, described golf main body has spherical ball, intermediate layer and shell, it is characterized in that, described golf, its coefficient of friction is more than 0.35, less than 0.60, there is on surface specific many pits, at least one deck of described spherical ball is rubber layer, by the JIS-C hardness that 9 of the thickness decile of described rubber layer are located, during distance (%) trace for the innermost point apart from described rubber layer, the R of the linear curve of approximation of being tried to achieve by least square methodn 2 more than 0.95, the hardness of the outermost point of described rubber layer is greater than the hardness of innermost point, and the hardness (Hm) in described intermediate layer is greater than the hardness (Hc) of described shell. |
