PROBLEM TO BE SOLVED: To provide a belt reduced in the worn amount of the surface thereof in contact with a pulley while maintaining the mechanical strength such as the rigidity of blocks and having a long service life. SOLUTION: This heavy load driving belt 1 comprises a center belt 3 and the blocks 2 installed at predetermined pitches along the longitudinal direction of the center belt. The blocks 2 are made of a resin composition formed by mixing a fiber-reinforced material of carbon fibers and aramid fibers and a friction reducing material of calcium carbonate in a thermoplastic resin. The 30-89 mass% thermoplastic resin, the 10-60 mass% fiber-reinforced material, and 1-50 mass% friction-reducing material are mixed in the total amount of the resin composition.
