Abstract
A golf ball includes, as a composing element, a hot-molded product of a rubber composition. The rubber composition contains a polybutadiene having 60 wt % or more of cis-1,4-bonds and 40 or more of a Mooney viscosity (ML1+4(100° C.)), unsaturated carboxylic acid and/or a metal salt thereof, an organic peroxide, and a monophenol based antioxidant. The golf ball can be produced with good workability because of no burn at the time of kneading the rubber composition, while preventing a reduction in rebound characteristic.
