The envelope layer is formed of an inner envelope layer, an intermediate envelope layer and an outer envelope layer. The inner, intermediate and outer envelope layers, the intermediate layer and the cover are each formed primarily of a resin material which may be of the same or different types, and the core is formed primarily of a rubber material. The golf ball has an excellent flight performance and also excellent controllability in the short game. In addition, it has a good feel on impact and an excellent scuff resistance.
