In a golf ball, dimples are arranged on a spherical polyhedron formed by dividing a surface of a sphere using small circles and great circles only on the equator, without arranging the dimples on a spherical polyhedron formed by dividing a surface of a sphere using great circles. The formed spherical polyhedron includes two spherical regular hexagons centered on a pole, twelve near-pole spherical isosceles triangles, twelve near-equator spherical pentagons, and twelve near-equator spherical isosceles triangles, in which the dimples are arranged. Thus, a dimple area ratio may be improved by 2 to 4%, compared to the prior art in which dimples are arranged in spherical polygons of a cubeoctahedron (or an octahedron) divided by great circles.
A golf ball having dimples arranged in spherical polygons, wherein, when an arbitrary point on a surface of a sphere is set to be a pole P, the spherical polygons are formed by dividing the surface of the sphere by a small circle line segment passing through Point 1 (latitude 0°, longitude 12°), Point 13 (latitude 40.340891453°, longitude 30°), Point 20 (latitude 59.5716612°, longitude 60°), Point 21 (latitude 59.5716612°, longitude 120°), Point 15 (latitude 40.340891453°, longitude 150°), and Point 6 (latitude 0°, longitude 168°);
A golf ball having dimples arranged in virtual spherical polygons formed by dividing a surface of a sphere using virtual dividing lines,
