To provide a novel method of manufacturing a golf ball, configured to form a spherical core having less variations in compression deformation amount and stabilized properties.
A method for manufacturing a golf ball comprises: a step of preparing a core rubber composition by blending (a) a base rubber, (b) an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a metal salt thereof as a co-crosslinking agent, (c) a crosslinking initiator, (d) a carboxylic acid and/or a salt thereof having a number-average particle size ranging from 15 μm to 60 μm, and further (e) a metal compound when needed; a step of molding the core rubber composition into a spherical core under specific conditions; and a step of forming at least one cover layer on the spherical core.
