Abstract
A friction transmission belt includes a compression layer forming a pulley contact portion, the compression layer includes an inner layer formed from a rubber composition and an outer layer provided on a pulley contact side of the inner layer and formed from a fiber member, and a ratio (M10 modulus/M50 modulus) of an modulus at 10% elongation in a belt longitudinal direction (M10 modulus) to an modulus at 50% elongation in the belt longitudinal direction (M50 modulus), of the rubber composition, is not less than 1.5.
