An object of the present invention is to provide a
golf ball cover resin composition containing an
ionomer resin with an excellent resilience and fluidity. Another object of the present invention is to provide a
golf ball using an
ionomer resin for a cover, with an excellent shot feeling, durability and resilience. The present invention provides a
golf ball cover resin composition comprising (A) an
ionomer resin consisting of 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; (B) a binary
copolymer composed of an olefin and an α,β-unsaturated
carboxylic acid having 3 to 8 carbon atoms and / or 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) a
zinc compound, wherein a content ratio ((A) / (B)) of (A) component to (B) component ranges from 50 / 50 to 80 / 20 in a
mass ratio and a content of (C) component ranges from 0.1 part to 20 parts with respect to 100 parts by
mass of a sum of (A) component and (B) component, and the golf ball cover resin composition has a melt flow rate (190° C., 2.16 kg) of 5 g / 10 min or more.
