ABSTRACT:
The invention provides a multi-piece solid golf ball having a rubber-based core encased by, in order, an intermediate layer and a cover. The core contains from 0.05 to 0.5 part by weight of sulfur per 100 parts by weight of the rubber base, has a hardness difference between the surface and center thereof, expressed in JIS-C hardness units, of at least 21 but not more than 30, and has a diameter of from 36 to 40 mm. The intermediate layer has a Shore D hardness of at least 47 but not more than 60, and a thickness of from 0.5 to 2.0 mm. The cover has a Shore D hardness of at least 53 but not more than 60, and a thickness of from 0.6 to 1.5 mm. The intermediate layer and cover satisfy the following condition: 120≦(Shore D hardness of intermediate layer×thickness of intermediate layer)+(Shore D hardness of cover×thickness of cover)≦150. The golf ball of the invention has, in particular, an excellent feel on impact and an excellent flight performance on shots taken with an iron.
