摘要：
A solid golf ball having good shot feel and durability as well as satisfactory flight performance and cut resistance. Which comprises a solid core and a cover covering the core, wherein the cover is formed from a heated mixture of: (A) an ionomer resin, (B) a thermoplastic elastomer having a carboxyl group or a thermoplastic elastomer having a terminal OH group, and (C) a block copolymer having a styrene-butadiene-styrene structure in which the polybutadiene block contains epoxy groups, or a block copolymer having styrene-isoprene-styrene structure in which the polyisoprene block contains epoxy groups, wherein the cover has a flexural modulus of from 50 to 300 MPa and a Shore D-scale hardness of from 40 to 60.
