<p>PROBLEM TO BE SOLVED: To provide a one piece golf ball which achieves a higher durability, a better shot touch, and excellent flying performance. SOLUTION: In the one piece golf ball produced by vulcanizing and forming a rubber composition containing a base rubber, a cross linking agent, an organic peroxide and an inorganic filler, the base rubber contains butadiene rubber (A) (1) with the weight average molecular weight (Mw) of 55×104×104 to 69×104 and the number average molecular weight (Mn) of 10×104 to 20×104 and polybutadiene rubber (B) (2) with the weight average molecular weight (Mw) of 70×104 to 120×104 and the number average molecular weight (Mn) of 13×104 to 25×104 at a rate of (A/B) 3/97 to 70/30 by weight.</p> |
