Golf ball

A golf ball having a core and a cover for covering the core, wherein the base resin of said cover comprises a mixture of the following three resins (A), (B) and (C) in a mixing weight ratio of 20 to 60, 10, to 60, and 5 to 50, respectively, and said cover having a stiffness modulus of 130 to 300 MPa and a Shore D hardness of 43 to 58, wherein

• Resin (A) is a high rigid ionomer resin or a resin mixture having a stiffness modulus of 300 to 500 MPa and a Shore D hardness of 60 to 70, obtained by neutralizing at least a part of carboxyl groups in a copolymer of an .alpha.-olefin and an .alpha.,.beta.-unsaturated carboxylic acid having 3 to 8 carbon atoms with a metal ion or a mixture thereof;
• Resin (B) is a moderate rigid ionomer resin or a resin mixture having a stiffness modulus of 65 to 150 MPa and a Shore D hardness of 50 to 60, obtained by neutralizing at least a part of carboxyl groups in a terpolymer of an .alpha.-olefin, an .alpha.,.beta.-unsaturated carboxylic acid having 3 to 8 carbon atoms and an .alpha.,.beta.-unsaturated carboxylic ester with a metal ion;
• and
• Resin (C) is a low rigid copolymer resin having a stiffness modulus of 1 to 50 MPa and a Shore D hardness of 5 to 30, comprising an .alpha.-olefin, an .alpha.,.beta.-unsaturated carboxylic ester having 3 to 8 carbon atoms and a polymerizable monomer containing a carboxyl group or a carboxylic anhydride group.
