摘要： A ball body is formed with a mold having upper and lower mold half. Dimples 16 having a shape inverted from the shape of the pimples of the mold are formed on the ball body. The dimples 16 in the vicinity of the equatorial line have a size in the meridional direction D1 being greater than a size in the latitudinal direction D2. The difference between the size in the meridional direction D1 and the size in the latitudinal direction D2 is 0.01 mm or greater and 0.50 mm or less. By grinding the ball body in the vicinity of the equatorial line, a flash generated on the seam resulting form the mold is removed. According to the grinding, the size in the meridional direction of the dimple 16 is reduced, and thus, plane shape of the dimple becomes closer to a perfect circle.

Circumferential central angles φ of the first horizontal plane (13) and the second horizontal plane (15) are 55 degrees or less. A total value Σφ of the circumferential central angles φ is 30 degrees to 330 degrees. An inclination angle α of the inclined surface (17) to a horizontal direction is 10 degrees to 60 degrees. A central angle θ between the horizontal planes (13) and (15) and an equator (E) is 1 degree to 8 degrees. A boundary corner portion of the horizontal planes (13) and (15) and the inclined surface (17) is subjected to rounding.
