PROBLEM TO BE SOLVED: To provide a toothed belt and its manufacturing method capable of enhancing the anti-abrasiveness and the resistance against cracking even in the high load operation by heightening the hardness of the tooth part, suppressing the vibration when teeth are in engagement, and hindering noise emission from the teeth in engagement. SOLUTION: The toothed belt 1 is equipped with a plurality of tooth parts 2 arranged at a certain spacing in the longitudinal direction and a back rubber layer 4 in which a core wire 3 are embedded and is structured so that a tooth cloth 5 is attached to the surface of the tooth parts 2, wherein the hardness of the rubber layer 4 is greater than the tooth parts 2, and the hardness of the rubber lessens continuously from the surface of the back rubber layer 4 to the surface of the tooth parts 2.
