| titleOfInvention | Multi-piece golf ball |
| abstract | An object of the present invention is to provide a golf ball showing low spin rate on driver shots and high spin rate on approach shots. The present invention provides a multi-piece golf ball comprising a spherical center, at least two envelope layers covering the spherical center, and a cover covering the envelope layers, wherein the envelope layers comprise at least a first envelope layer covering the spherical center, and a second envelope layer covering the first envelope layer, a material hardness (H0) of the spherical center, a material hardness (H1) of the first envelope layer, and a material hardness (H2) of the second envelope layer satisfy an equation of H0>H1>H2, and the material hardness (H2) of the second envelope layer is lowest among the material hardness of the center constituent material and material hardness of envelope layer constituent materials. |
