Multi-piece solid golf ball

A multi-piece solid golf ball comprising a core, an intermediate layer, and a cover, wherein the core is formed of a rubber composition into a single layer or a plurality of layers, the intermediate layer and the cover are both formed of a resin composition, and a relationship between a core surface hardness, a surface hardness of a sphere (intermediate layer-encased sphere) obtained by encasing the core with the intermediate layer, and a surface hardness of a sphere (ball) obtained by encasing the intermediate layer-encased sphere with the cover satisfies the following condition:

• ball surface hardness<surface hardness of intermediate layer-encased sphere>core surface hardness
• (where the surface hardness of each sphere means Shore C hardness)
• and the core has a hardness profile in which, letting a Shore C hardness at a core center be Cc, a Shore C hardness at a midpoint M between the core center and a core surface be Cm, respective Shore C hardnesses at positions 2 mm, 4 mm, and 6 mm inward from the midpoint M be Cm−2, Cm−4, and Cm−6, respective Shore C hardnesses at positions 2 mm, 4 mm, and 6 mm outward from the midpoint M be Cm+2, Cm+4, and Cm+6, and a Shore C hardness at the core surface be Cs, and defining surface areas A to F as follows:
• surface area A:
• ½×2×(Cm−4−Cm−6)
• surface area B:
• ½×2×(Cm−2−Cm−4)
• surface area C:
• ½×2×(Cm−Cm−2)
• surface area D:
• ½×2×(Cm+2−Cm)
• surface area E:
• ½×2×(Cm+4−Cm+2)
• surface area F:
• ½×2×(Cm+6−Cm+4)
• the following condition is satisfied:
• (surface area E+surface area F)−(surface area A+surface area B)≥3.0
• and letting a deflection (mm) when the core is compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf) be C (mm), the following two conditions are satisfied:
• Cs−Cc≥28.0
• C×(Cs−Cc)≥132.0.
