Abstract
A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and embedded in the belt body. The belt tension T0.2 per 1 mm belt width at 0.2% of a belt extension rate is 70 N/mm or more. The belt tension T0.5 per 1 mm belt width at 0.5% of the belt extension rate is 220 N/mm or more. The ratio of the belt tension T0.2 to the belt tension T0.5 is 0.33 or more.
