Abstract:
1. A golf ball having numerous dimples, which include polygonal dimples, provided on the surface thereof, wherein a phantom spherical face of the golf ball is comparted into multiple spherical regular polygons with comparting lines formed by casting a reflection of sides of a semiregular polyhedron inscribed in the phantom spherical face onto the phantom spherical face, the spherical regular polygons include the dimples arranged therein; wherein said spherical regular polygons include multiple first spherical regular polygons and multiple second spherical regular polygons that have a different number of vertices from that of said first spherical regular polygons formed with said comparting lines, all the first spherical regular polygons include the dimples arranged therein in a substantially equivalent manner with each other, and all the second spherical regular polygons include the dimples arranged therein in a substantially equivalent manner with each other; wherein on each of said first spherical regular polygons, regular polygonal dimples each having the same number of vertices as the number of vertices of one of said first spherical regular polygons are mainly arranged, and on each of said second spherical regular polygons, regular polygonal dimples each having the same number of vertices as the number of vertices of one of said second spherical regular polygons are mainly arranged and the proportion of the polygonal dimples with respect to the total number of the dimples is equal to or greater than 50%.
