Abstract:
In a multi-piece solid golf ball having a core and four successive layers encasing the core—an inner envelope layer, an outer envelope layer, an intermediate layer and a cover, the inner envelope, outer envelope and intermediate layer are each formed of different highly neutralized resin materials, and the cover thickness is larger than the respective thicknesses of the inner envelope layer, outer envelope layer and intermediate layer. Also, the value (A)−(B) obtained by subtracting the material hardness (B) of the softest layer among the inner envelope layer, outer envelope layer and intermediate layer from the material hardness (A) of the cover is a Shore D hardness of 13 or more. This golf ball holds down the spin rate on full shots with a driver by amateur golfers having modest head speeds, and also has a soft and good feel at impact.

Claim (Index 4):
The golf ball of  claim 1 , wherein the material hardness of the intermediate layer on the Shore D hardness scale is from 50 to 60.
