Abstract
The present invention provide a golf ball which can improve the mold releasing property in a press molding to ensure an increased productivity without decreasing a flight performance and durability. The golf ball has a part including a vulcanized rubber composition. The vulcanized rubber composition includes 100 parts by weight of a base rubber and 100 parts by weight or less of unsaturated carboxylic acid compounds. The unsaturated carboxylic acid compounds includes Component (A) of magnesium (meth) acrylate, and Component (B) of α, β-unsaturated carboxylic alkyl ester. The content ratio of the Component (A) to the Component (B) (A/B) is 0.2 to 4.
