Multi-piece solid golf ball

A multi-piece solid golf ball comprising a core, an intermediate layer, and a cover, a large number of dimples being formed on an outside surface of the cover, wherein a relationship between a surface hardness of an intermediate layer-encased sphere and a surface hardness of the ball satisfies the following condition:

• (surface hardness of ball)<(surface hardness of intermediate layer-encased sphere)
• (where the surface hardnesses mean Shore C hardnesses),
• wherein when an initial velocity of the ball is 76.5 to 77.724 m/s, a deflection is at least 2.7 mm when the ball is compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf), and a value of (initial velocity of core×weight of core) is denoted by Ciw, a value of [(initial velocity of intermediate layer-encased sphere−initial velocity of core)×(weight of intermediate layer-encased sphere−weight of core)] is denoted by 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)] is denoted by CViw, the following condition is satisfied:
