ABSTRACT:
The present invention provides a multi-piece solid golf ball having a core, an inner cover layer and an outer cover layer. The core is made of a material obtained by molding under applied heat a rubber composition containing (a) a base rubber containing polybutadiene having a stress relaxation time (T80) of 3.5 or less, (b) an unsaturated carboxylic acid and/or a metal salt thereof, and (c) an organic peroxide. The inner cover layer has a Shore D hardness of from 50 to 80, the outer cover layer has a Shore D hardness of from 35 to 60 which is lower than the Shore D hardness of the inner cover layer, and the inner cover layer is formed primarily of a specific, highly neutralized resin mixture. The golf ball as a whole has an excellent rebound, a good, soft feel on impact, and an outstanding spin performance, and is capable of achieving an increased distance.
