The present invention provides a solid golf ball having exceptional rebound characteristics
and flight performance, as well as good shot feel. The present invention relates
to a solid golf ball comprising at least one layer of a core, and at least one
layer of a cover formed on the core, wherein at least one layer including the inmost
layer of the core is formed by vulcanizing a rubber composition comprising a base
rubber, a co-crosslinking agent, a vulcanization initiator and a filler, the core
has a center hardness in JIS-C hardness of 40 to 60, a surface hardness in JIS-C
hardness of 80 to 95 and a hardness difference (B-;A) between a hardness in JIS-C
hardness at a distance of 5 mm from the center point of the core (B) and the center
hardness (A) of not less than 1 to less than 10.
