摘要

PROBLEM TO BE SOLVED: To obtain a multipieces solid golf ball which has a soft and good fitting feel and has less dependence on a head speed even when a ball is shot with any club from a driver to a putter. SOLUTION: This golf ball includes an inside core ball 1, multiple solid cores 3 consisting of at least >= layers of enclosing layers 2 covering this inside core ball 1 and a cover 6 consisting of an inside layer 4 covering these cores and an outside layer 5 covering this inside layer 4. The inside core ball 1 is formed to the hardness of 3.5 to 10mm in the deformation rate at the time of loading with 100kg load. In addition, the enclosure layers 2 are formed to the highest hardness of >=60 in Shore D hardness. The inside layer hardness of the cover 6 is <=58 in Shore D hardness and the outside layer hardness of the cover 6 is <=60 in Shore D hardness.
