Claim:
A solid golf ball, comprising: a core including at least one layer; and a cover including at least one layer, the cover being provided to cover the core, wherein the at least one layer of the core is prepared by vulcanization-molding a rubber composition, the rubber composition comprising: (a) a base rubber; (b) a co-crosslinking agent; (c) an organic peroxide; (d) a filler; and (e) a disulfide compound represented by the following formula (I): R 1 —S—S—R 2 (I) wherein R 1 is an optionally substituted aromatic hydrocarbon group, R 2 is an optionally substituted aliphatic hydrocarbon group having four or more carbon atoms, and R 1 is a group different from R 2 , or a compound represented by the following formula (III): wherein, in the formula (III), R 1-vi to R 1-x may be the same as or different from one another and each represents H or a substituent, at least one of R 1-vi to R 1-x is a substituent, and at least one of the substituents is a halogen group or trihalomethyl group; R 2-vi to R 2-x may be the same as or different from one another and each represents H or a substituent, at least one of R 2-vi to R 2-x is a substituent, and at least one of the substituents is a halogen group or trihalomethyl group; and the phenyl group having R 1-vi to R 1-x is different from the phenyl group having R 2-vi to R 2-x .
