The golf ball including a core and a cover surrounding the core is characterized in that the cover is constituted by a mixture of an ionomer resin, a thermoplastic elastomer with a rubber segment, and a tackifier having a softening point of not more than 100° C. The peak temperature of the loss tangent is not more than 5° C., and the Shore D hardness is at least 35 and not more than 60.
