Abstract
A golf ball having an intermediate layer of thermoplastic resin between a thread-wound central core and an outer polyester elastomer layer. The thermoplastic resin has a substantial melt flow initiation temperature of 160.degree. C. or less, the substantial melt flow initiation temperature being the minimum temperature at which the melt index under a load of 4350 g. becomes 1 g/10 mins or more, and has a high adhesion property to the polyester elastomer cover. It is preferable that the thermoplastic resin have a resilience of 30% or more and that the intermediate layer of thermoplastic resin be within the range of 0.1 to 1.0 mm. This golf ball has excellent cutting resistance, 'click' characteristics and impact resilience.
