Regarding arrangement of dimples by dividing a surface of a golf ball in the present invention, the dimples are arranged by dividing a surface of a sphere by triangular concave sectors in a jig-jag form, which does not divide the surface of the sphere by great circles (GC). The ball is capable of easily obtaining lift force and improving driving distance by increasing the surface of the sphere and, generally, a dimple area ratio. |
