A multi-piece solid golf ball includes an inner sphere (1), at least one enclosure layer (2), a cover inner layer (4), and a cover outer layer (5). The inner sphere has a deflection of 3.5-8.0 mm under a load of 100 kg. The enclosure layer is formed of an ionomer resin with a high acid content. The cover outer layer has a Shore D hardness of 40-60, and the cover inner layer has a lower Shore D hardness of 10-50 than the outer layer. The golf ball is improved in flight distance, spin performance, scuff resistance and durability against repetitive shots while giving a soft pleasant feel when hit with any club ranging from a driver to a putter. |
