A polyamide resin composition of the present invention comprises 60 to 85% by mass of a polyamide resin (A), 20% by mass or more of an olefin-based ionomer (B) and 5 to 20% by mass of an impact resistant material (C) in 100% by mass of the polyamide resin composition, and contains 20% by mass or more of an aliphatic copolymerized polyamide (A-1) in 100% by mass of the polyamide resin (A).

A golf ball material contains (I) a multi-component copolymer having conjugated diene units, non-conjugated olefin units and aromatic vinyl units; and (II) a binary copolymer of an olefin and an α,β-unsaturated carboxylic acid of 3 to 8 carbons and/or a ternary copolymer of an olefin, an α,β-unsaturated carboxylic acid of 3 to 8 carbons and an ester of the α,β-unsaturated carboxylic acid, or a metal neutralization product thereof.

The conjugated diene units include butadiene units, the non-conjugated olefin units include units selected from the group consisting of ethylene, propylene and 1-butene units, and the aromatic vinyl units include styrene units. The content of the conjugated diene units in the multi-component copolymer (I) is 5 wt % or more. This golf ball material is soft and has an excellent rebound resilience. Golf balls which use this material in the cover provide golfers with a competitive edge.
