摘要: A golf ball 2 includes a spherical core 4 and a cover 6 covering the core 4 and including an inner cover 8 and an outer cover 10 positioned outside the inner cover 8. The core 4 is obtained by crosslinking a rubber composition. The rubber composition includes a base rubber (a), a co-crosslinking agent (b), a crosslinking initiator (c), and a carboxylate (d). The co-crosslinking agent (b) is: (b1) an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms; or (b2) a metal salt of an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms. The amount of the carboxylate (d) is equal to or greater than 1 parts by weight but less than 40 parts by weight per 100 parts by weight of the base rubber (a). A hardness of an innermost layer of the cover is equal to or less than a surface hardness of the core.

摘要: The surface of a golf ball 2 is divided by four comparting great circles CG into six spherical quadrangles Ss and eight spherical triangles St. The eight spherical triangles St are composed of four first spherical triangles St1 and four second spherical triangles St2. Dimple patterns of the six spherical quadrangles Ss are the same. Dimple patterns of the four first spherical triangles St1 are the same. Dimple patterns of the four second spherical triangles St2 are the same. The dimple pattern of each first spherical triangle St1 is different from the dimple pattern of each second spherical triangle St2.
