The present invention provides a multi-piece solid golf ball having a core, an envelope layer encasing the core, an intermediate layer encasing the envelope layer, and a cover which encases the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is composed overall of an inner layer and an outer layer which are each formed primarily of a rubber material, with the outer core layer being harder than the inner core layer. The envelope layer, intermediate layer and cover have respective thicknesses which satisfy the condition: cover thickness<intermediate layer thickness<envelope layer thickness, and have respective material hardnesses (Shore D hardness) which satisfy the condition: envelope layer material hardness<intermediate layer material hardness>cover material hardness. The golf ball has a lower spin rate on full shots with a driver, further increasing the distance traveled by the ball. Moreover, it has a good controllability, maintaining in particular a straight trajectory on full shots, and also has an excellent scuff resistance. |
