An object of the present invention is to provide a rubber composition having high transparency and toughness. The composition of the present invention comprises: a low cis isoprene rubber component, and is selected from the group consisting of butadiene rubber, 1,2-polybutadiene rubber, styrene butadiene rubber, acrylonitrile butadiene rubber, a rubber polymer component of a group consisting of a hydrogenated nitrile rubber, a urethane rubber, an ethylene propylene rubber, an ethylene propylene diene rubber, a chloroprene rubber, and a natural rubber, and a low cis isoprene When the total mass of the rubber component and the rubber polymer component is 100 parts by mass, the amount of the low cis isoprene rubber component is in the range of 45 to 95 parts by mass, and substantially no cerium oxide is contained. |
