Claim Text:
1. A golf ball resin composition comprising: (A) a polyamide resin, (B) at least one member selected from the group consisting of (b-1) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (b-2) a metal ion-neutralized product of a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms, (b-3) a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester, and (b-4) a metal ion-neutralized product of a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester, and (C) an organically modified layered silicate in an amount of 0.1 part by mass to 50 parts by mass with respect to 100 parts by mass of a total of (A) component and (B) component, and a fatty acid and/or a metal salt of a fatty acid, wherein a content of (A) component with respect to 100 mass % of a total of (A) component and (B) component ranges from 15 mass % to 80 mass %, a slab hardness of the golf ball resin composition is 65 or more and 80 or less in Shore D hardness, a value (X/A) obtained by dividing a flexural modulus X (MPa) of the golf ball resin composition by the content of (A) component (A: 15 mass % to 80 mass %) is 12.5 or more, and (C) the organically modified layered silicate includes a layered silicate treated with an organic onium ion, and the organic onium ion includes an organic ammonium ion having a total of 11 to 30 intramolecular carbon atoms.
