摘要: An object of the present invention is to provide a novel golf ball that controls the spin rate on the approach shots while suppressing the change in the spin rate on the driver shots and a method for producing the same. The present invention provides a golf ball having a cover containing a resin component and a filler, wherein the filler is oriented roughly parallel to a surface of the cover. The cover having anisotropy behaves like a hard material against the deformation in the compression direction on the driver shots and behaves like a soft material against the deformation in the shear direction on the approach shots. The present invention also provides a method for producing a golf ball, comprising compression molding a cover composition containing a resin component and a filler to mold a shell, and compression molding a core covered with a plurality of shells to mold a cover.
