Abstract
A golf ball is molded in a mold comprising a pair of removably joined mold sections. The golf ball has a plurality of dimples, the dimples being arranged in a polyhedral arrangement. The golf ball is free of a great circle which does not intersect with the dimples. The dimples (D,) lying across the parting line (P) between the mold sections, except for the dimples (D,) whose center lies on the parting line, are shifted upward or downward from the parting line or reduced in diameter so that these dimples are located outside the parting line (P). The dimple surface coverage is at least 71%. A golf ball having high symmetry and excellent flight performance can be prepared using a simple mold.
