Golf ball

Abstract

An object of the present disclosure is to provide a golf ball having improved durability and substantially not lowered resilience. The present disclosure provides a golf ball comprising a core and at least one cover layer positioned outside the core, wherein the at least one cover is formed from a cover composition containing one or more ionomer resins, the ionomer resin comprises a copolymer (P) having a structural unit (A) derived from ethylene and/or an α-olefin having 3 to 20 carbon atoms and a structural unit (B) having a carboxyl group and/or a dicarboxylic anhydride group as an essential constitutional unit, and at least a part of the carboxyl group and/or the dicarboxylic anhydride group in the copolymer (P) is neutralized with at least one kind of metal ion selected from Group 1, Group 2 and Group 12 in the periodic table, and a loss modulus E″ at a temperature of 0° C. is 3.40×107 Pa or less, wherein the loss modulus E″ at the temperature of 0° C. is determined by measuring a dynamic viscoelasticity of the cover composition under specific conditions.
