A multi-piece golf ball has a core ( 3 ), an interlayer ( 5 ), and a cover ( 7 ), the core ( 3 ) being provided with a spherical main part ( 31 ) and a plurality of ribs ( 32 ) formed on the main part ( 31 ), the interlayer ( 5 ) being accommodated in depressions ( 33 ) surrounded by the ribs ( 32 ) and having a thickness substantially the same as the height of the ribs ( 32 ), each of the ribs ( 32 ) extending in such a manner that the width thereof becomes greater from the cover towards the core, each of the depressions ( 33 ) being formed into a cone-like shape by side faces of the ribs ( 32 ), and the hardness of the interlayer ( 5 ) being less than that of the core ( 3 ). This structure achieves satisfactory soft feeling and high bounce resilience.
