PROBLEM TO BE SOLVED: To provide a golf ball traveling a great flight distance on driver shots.SOLUTION: The present invention provides a golf ball in which at least one constituting member therefor contains: (A) a polyamide resin, and (B) at least one member selected from the group consisting of (b-1) a binary copolymer composed of an olefin and an α,&bgr;-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,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms, (b-3) a ternary copolymer composed of an olefin, an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,&bgr;-unsaturated carboxylic acid ester, and (b-4) a metal ion-neutralized product of a ternary copolymer composed of an olefin, an α,&bgr;-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,&bgr;-unsaturated carboxylic acid ester, where 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 is 65 or more and 80 or less in Shore D hardness, and a value (X/A) obtained by dividing a flexural modulus X (MPa) by the content of (A) percentage component (A: 15 mass% to 80 mass%) is 12.5 or more. |
