The present invention provides a golf ball which exhibits excellent
durability and provides a long ball distance. The golf ball includes a
core and an outer layer wrapping the core, wherein the outer layer is
made of a resin composition containing cation-treated phillosilicate
having a Shore D hardness of 56 or higher and 75 or lower. In particular,
by use of a resin composition containing the cation-treated
phillosilicate for a cover layer, the resultant golf ball has high
hardness and high stiffness, exhibits excellent flight performance, and
also has high durability.
