The invention provides a multi-piece solid golf ball composed of a solid core, a cover, at least one intermediate layer interposed therebetween, and a plurality of dimples on a surface of the ball. The respective initial velocities (m/s) of the core, a sphere I composed of the core encased by the intermediate layer, and the golf ball satisfy formula A below, and the respective deflections (mm) of the core, the sphere I composed of the core encased by the intermediate layer, and the golf ball, when compressed under a final load of 130 kg from an initial load of 10 kgf, satisfy formula B below: (initial velocity of core−initial velocity of sphere I)2+(initial velocity of sphere I−initial velocity of golf ball)2<0.40;   Formula A: 0.30<(deflection of core−deflection of sphere I)2+(deflection of sphere I−deflection of golf ball)2<0.70.   Formula B: The golf ball of the invention has a good feel, an excellent spin performance on approach shots and an excellent distance, in addition to which it has an excellent scuff resistance and durability. |
