摘要： A half shell having a top part thickness of 65% or greater and 95% or less and a side part thickness of 100% or greater and 120% or less of the nominal thickness T of the cover is formed. Next, the core 4 composed of the center and the mid layer is fitted to two pieces of the half shell 46. Next, the core 4 and the half shell 46 are placed into a mold 32. Next, the mold 32 is clamped at a speed of 0.5 mm/sec or greater and 2.0 mm/sec or less. The thermoplastic resin composition of the half shell 46 is heated while being compressed in the spherical cavity to result in flow. This resin composition is hardened to give a cover having a thickness of 0.1 mm or greater and 0.8 mm or less. Dimples are formed on the cover by way of pimples 40. Recessed parts are formed on the mid layer by way of the pimples 40.

摘要： The rubber composition for use in manufacturing a solid core of a multilayer-structured golf ball or a one-piece golf ball contains a co-curing agent and preferably an organic sulfur compound micro-encapsulated within a thermoplastic resin whose softening point is in a range of 80-250° C. This improves dispersibility of the co-curing agent and the organic sulfur compound within the rubber composition, and enables adjustment of a crosslinking pattern of rubber molecule main chains, so that rebound performance of the golf ball is improved.
