Claim Text:
1. A golf ball comprising: a spherical ball body having a spherical land surface; and a dimple pattern of a plurality of dimples distributed on the spherical land surface, wherein a regular polyhedron having polygon faces is virtually inscribed in the spherical ball body, and the spherical land surface is divided into a plurality of identical spherical land surface parts by means of the polygon faces of the regular polyhedron, respectively, wherein on each spherical land surface part, almost all of the dimples are formed as non-circular dimples having a width of more than 1.5 mm but not more than 2.5 mm, and having a length of more than 2 times the width, wherein on each spherical land surface part, the non-circular dimples comprise a plurality of petal shaped dimples constructed of a pair of arc lines extending radially from the center of the spherical land surface part, and disposed so as to make vortices generated in the dimples flow out in at least two different directions.
