An object of the present invention is to provide a golf ball excellent in a shot feeling and resilience. The present invention provides a golf ball resin composition comprising (A) at least one resin component selected from the group consisting of (a-1) a binary copolymer composed of an olefin and an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, (a-2) an ionomer resin consisting of a metal ion-neutralized product of the binary copolymer, (a-3) a ternary copolymer composed of the binary copolymer components and an α,&bgr;-unsaturated carboxylic acid ester, and (a-4) an ionomer resin consisting of a metal ion-neutralized product of the ternary copolymer components; and (B) a basic metal salt of a fatty acid, and having a spin-lattice relaxation time (T1) of 13C nucleus of 5.56 seconds or shorter measured by a High resolution solid state nuclear magnetic resonance (NMR) method. |
