    摘要： The present invention relates to a mold having a parting line along dimples which allows manufacturing of golf balls free from burrs, and to golf balls manufactured using such a mold. The mold of the present invention is provided with a spherical cavity inside thereof; and an upper mold and a lower mold separable from each other, wherein a plurality of convex portions for forming dimples is provided in the inner surface of the cavity, at least one of the plurality of convex portions lies over the equator of the cavity, a parting line, which corresponds to the boundary between the upper mold and the lower mold, extends along the inner surface of the cavity, the parting line comprises first lines extending along the peripheries of the convex portions lying over the equator and second lines connecting the first lines, and the first line is disposed apart from the periphery by a distance of 0.1 to 0.5 mm.
