Abstract: The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.
