The present invention provides a rubber composition for a golf ball that has both spin characteristics and durability when hitting a golf ball and has high productivity of the ball, and a golf ball using the same. SOLUTION: (A) base rubber, (B) two different kinds of α, β-unsaturated carboxylic acid metal salt having 3 to 8 carbon atoms, (C) at least one binding site having 9 or more carbon atoms A fatty acid metal salt and (D) a crosslinking initiator, and among the above component (B), the unsaturated carboxylic acid metal salt having the larger blending mass is (B-1) and the blending mass is small. When the unsaturated carboxylic acid metal salt is (B-2), the value of (B-2) / (B-1) is 4 to 20% by mass and (B-2) / (C ) Is 20 to 115% by mass. [Selection figure] None |
