Claim:
A golf ball of the type having a large number of convex parts projecting from the spherical surface, said convex parts assuming a round or non-round shape as viewed from above, wherein the improvement comprises the large number of convex parts being arranged such that an upper surface of each of the convex parts has a certain radius of curvature and coincides with a hypothetical spherical surface covering said spherical surface, at least part of the large number of convex parts form strings of convex parts connected to each other through a part thereof, and the strings of convex parts form at least one great circle which is substantially continuous on the spherical surface; wherein more than one of the strings of convex parts are formed such that they cross each other to form polygonal areas each consisting of small areas; wherein the areas divided by the strings of convex parts have concave parts arranged therein which assume a round or non-round shape as viewed from above.
