ABSTRACT:
In a wound golf ball comprising a center ball (1), thread rubber (2), and a cover, the cover consists of a first layer (3) on the wound center and a second layer (4) on the first layer. The first layer (3) is 0.5-3.0 mm thick. The second layer (4) is 10-300 .mu.m thick. The second layer (4) may be formed by either (a) injection molding a resin composition to enclose the first layer (3) or (b) press molding a resin composition film wrapped around the first layer (3). Dimples may be embossed in the first layer (3) before the second layer (4) is formed thereon. Preferably, dimples are embossed after the second layer (4) is formed on the first layer (3). The ball affords improved spin and flying distance and is fully durable.
