Abstract: The present invention relates to a frictional power transmission belt containing an extensible layer forming a belt back surface, a compressive rubber layer formed on one surface of the extensible layer and frictionally engaging at the lateral surface thereof with pulleys, and a tension member embedded between the extensible layer and the compressive rubber layer along the belt length direction, in which a surface of at least a part of the compressive rubber layer to be in contact with pulleys is coated with a fiber/resin mixture layer that contains a resin component and heat-resistant fibers having a softening point or a melting point higher than a vulcanization temperature in a mixed state, and the heat-resistant fibers contain a fiber embedded so as to extend from the fiber/resin mixture layer to the compressive rubber layer.
