To provide a golf ball which has a suitable spin rate in a short game and can thus manifest a good controllability, yet which holds down the spin rate on shots with a driver, enabling an excellent flight performance to be achieved, and which moreover provides a good feel at impact.
In a golf ball including a core, an intermediate layer and a cover, the intermediate layer formed of an ionomer resin material having a high degree of neutralization is combined with a cover formed of a material that includes a first ionomer resin having a high unsaturated carboxylic acid content and a second ionomer resin having a low unsaturated carboxylic acid content. The golf ball is able to achieve a lower spin rate on full shots with a driver (W#1) without reducing the spin performance on approach shots in the short game, provides high levels of both flight performance and controllability, and also has a good feel at impact.
