Claim:
A golf ball comprising a core, a mid layer positioned outside the core, and a cover positioned outside the mid layer, wherein a difference between: a JIS-C hardness H(5.0) at a point that is located at a distance of 5 mm from a central point of the core; and a JIS-C hardness Ho at the central point is equal to or greater than 6.0, a difference between: a JIS-C hardness H(12.5) at a point that is located at a distance of 12.5 mm from the central point; and the hardness H(5.0) is equal to or less than 4.0, a difference between a JIS-C hardness Hs at a surface of the core and the hardness H(12.5) is equal to or greater than 10.0, a difference between the hardness Hs and the hardness Ho is equal to or greater than 22.0, there is no zone in which a hardness decreases from the central point toward the surface, and a Shore D hardness H 2 of the mid layer is greater than a Shore D hardness H 3 of the cover.
