The invention provides an improved golf ball which exhibits satisfactory ball characteristics, particularly, repulsion property and scuff resistance. The golf ball has a cover made of the polyurethane prepared by curing a urethane prepolymer having an isocyanate group at a terminal thereof with an amine-type curing agent represented by the following general formula: <paragraph lvl="0"><in-line-formula>H2N-R1-polyether moiety-R2-NH2 </in-line-formula>where R1 and R2 are independently hydrocarbon groups each having 1 to 6 carbon atoms. The amine-type curing agent causes curing at such a speed as to ensure a pot life allowing necessary operations to be performed.
