    摘要： A thread-wound golf ball, such as a balata-covered golf ball, formed of a center 1a, a rubber thread layer 1b covering the center 1a, and a cover 2 is provided. The center 1a has an outer diameter of 28-35 mm and a Shore A hardness of 10-50. The cover 2 is formed of a mixture containing ionomer resin, thermoplastic elastomer and tackifier and has a Shore D hardness of 45-60. As such, the golf ball exhibits great carry distance with good shot feel, provides high spin rate when shot from the rough or in a raining condition, and that easily comes to a halt.
