The resin component of the cover consists of 30 to 100% by weight of an ethylene-methacrylic acid-acrylate terpolymer ionomer resin having a flexural modulus of 2,500-14,000 psi and a Shore D hardness of 20-59 and 70 to 0% by weight of an ethylene-(meth)acrylic acid copolymer ionomer resin having a flexural modulus of 20,000-29,000 psi and a Shore D hardness of 56-62. The ball is excellent in spin receptivity, burring resistance, and feel on hitting.
