Abstract
The solid golf ball of the invention is a one-piece golf ball or a multi-piece golf ball having a solid core enclosed directly in a cover or with an intermediate layer disposed therebetween. The one-piece golf ball or the solid core and/or intermediate layer of the multi-piece golf ball is formed of a rubber composition comprising a base rubber, an unsaturated carboxylic acid or a metal salt thereof, and a sulfur halide. Owing to the optimal degree of deformation and high resiliency of the elastic rubber portion therein, the solid golf ball has an excellent feel and an excellent flight performance.
