Abstract
In a solid golf ball comprising a solid core and a cover, the solid core has a multilayer construction which includes a center core and an outer core of at least one layer that encloses the center core. The center core is formed primarily of a resin and has a diameter from 3 mm to less than 15 mm. The outer core is formed of a rubber composition based on polybutadiene. The center core has a surface hardness which is higher than the hardness of an innermost layer of the outer core. The ball has a high-pitched click and a soft feel.
