    Abstract: A golf ball includes a spherical core, and a cover covering the spherical core. The spherical core is formed from a rubber composition including a base rubber, a co-cross-linking agent, a cross-linking initiator, an unsaturated fatty acid and/or a metal salt thereof, and an aromatic carboxylic acid and/or a metal salt thereof, the co-cross-linking agent includes an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a metal salt thereof, the unsaturated fatty acid and metal salt thereof excludes an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and a metal salt thereof, and the rubber composition includes a metal compound when the co-cross-linking agent contains only an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms.
