<p>The present invention provides a two piece golf ball having an excellent shot feel, which comprises a core and a cover, wherein the core has a deformation (compression deformation) of 3.7 to 4.5 mm caused by applying from 10 kg of an initial load to 130 kg of a final load, prepared from a rubber composition comprising 100 parts by weight of a cis-1,4-poly butadiene rubber and 20 to 30% by weight of a metal salt of an unsaturated carboxylic acid, and the cover has a stiffness modulus of 3,700 to 4,500 kg/cm<2> and a thickness of 2.2 to 2.9 mm.</p> |
