1. A multi-piece solid golf ball comprising a core, an intermediate layer, and a cover, wherein an initial velocity of the ball is not more than 76.0 m/s, a deflection when the ball is compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf) is at least 2.8 mm, and letting a value of (initial velocity of core×weight of core) be Ciw, a value of [(initial velocity of intermediate layer-encased sphere−initial velocity of core)×(weight of intermediate layer-encased sphere−weight of core)] be Miw, and a value of [(initial velocity of ball−initial velocity of intermediate layer-encased sphere)×(weight of ball−weight of intermediate layer-encased sphere)] be CViw, the following condition is satisfied:
Ciw+Miw+CViw≤2,550.
