    • Golf ball 2 has core 4, cover 6 and paint layer 12. The base polymer of the cover 6 includes a thermoplastic polyurethane elastomer. The cover includes 0.1 parts by weight or more and 10 parts by weight or less of a hindered amine heat and light resistance stabilizer having a hindered phenol group, per 100 parts by weight of the base polymer. Preferably, the hindered amine heat and light resistance stabilizer has two or more hindered phenol groups in the molecule. It is preferred that the cover 6 further includes an ultraviolet ray absorbing agent and a heat resistance stabilizer. Provided that the molar concentration of the hindered amine heat and light resistance stabilizer is defined as A, and the molar concentration of the ultraviolet ray absorbing agent is defined as B, the molar ratio (A/B) is preferably 0.01 or greater and 2.5 or less. The cover 6 may further include a heat resistance stabilizer.
