An object of the present invention is to provide a golf ball traveling a great distance on driver shots. The present invention provides a golf ball comprising a constituting member formed from a rubber composition containing (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, and (c) an crosslinking initiator, wherein (b) the α, β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or the metal salt thereof meets the following conditions (1) and (2) in a volume based distribution, when measuring a particle size thereof with a laser diffraction particle size analyzer; (1) a mode particle size is more than 10 μm and 50 μm or less, and (2) a volume ratio of particles having a particle size ranging from 6 μm to 300 μm is 60% or more.
