摘要： An object of the present invention is to provide a golf ball having excellent resilience. The present invention provides a golf ball comprising a spherical core and at least one cover covering the spherical core, wherein the spherical core is formed from a rubber composition containing (a) a base rubber, and (b) a co-crosslinking agent containing (b1) a carboxylic acid represented by a structural formula (1) and/or a metal salt thereof. [In the formula (1), A1 to A4 each independently represents a nitrogen atom or a carbon atom. X1 represents a single bond or a divalent organic group. R1 represents a hydrogen atom or a monovalent organic group. It is noted that at least one of A1 to A4 is the carbon atom, and X1 and R1 bond to the carbon atom. n represents an integer of 0 to 3. When n is 2 or more, a plurality of R1 may be identical to or different from each other, and a plurality of R1 may bond to each other to form a ring structure.]
