Abstract:
The invention provides a golf ball in which an intermediate layer formed of a highly neutralized resin mixture obtained by using two nonionic resins of differing weight-average molecular weights and breadths of molecular weight distribution (weight-average molecular weight/number-average molecular weight) as the base resin and adding thereto an organic acid or a metal salt thereof and a basic inorganic metal compound capable of being neutralized is combined with a cover formed of an ionic resin having a weight-average molecular weight in a specific range and a breadth of molecular weight distribution (weight-average molecular weight/number-average molecular weight) in a specific range. The golf ball material of the invention has an excellent rebound and durability.
