An object of the present invention is to provide a 
golf ball resin composition excellent in shot feeling and resilience. The 
golf ball resin composition includes (A) at least one resin component selected from the group consisting of (a-1) a binary 
copolymer composed of an olefin and an α,β-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 components, (a-3) a ternary 
copolymer composed of the binary copolymer components and an α,β-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 storage modulus E′ (Pa) and a loss modulus E″ (Pa) satisfying a following expression;log(E′ / E″2)≧−5.84when measured in a tensile mode using a 
dynamic viscoelasticity measuring apparatus.
