摘要： A hollow golf ball comprising a hollow core and a cover layer that possesses good shot feel, an increased moment of inertia, and a high launch angle at the time of hitting. Immediately after impact, the hollow golf ball has a small spin amount. The specific hollow core reduces the rate of spin dumping between the ascending and descending of the ball, which results in increased flight distance. The hollow golf ball has a hollow core and a cover layer formed on the core, wherein the hollow core is composed of a hollow portion having a diameter of 5 to 30 mm and a core outer layer portion surrounding said hollow portion.
