To provide a transmission belt in which short fiber is planted on a belt transmission surface and exposed, noise during a belt is traveling is reduced, and durability is enhanced.

The transmission belt 1 having a rubber layer 3 constituted by embedding core wires 3 along a longitudinal direction of a belt, a shaped part 6 comprising a rib part disposed adjacent to the rubber layer 3 and extending the longitudinal direction of the belt or cog parts arranged in a predetermined interval in the longitudinal direction of the belt has an inner layer constituted by flowing rubber in a wave shape and a surface layer constituted by planting the short fiber into the shaped part 6 in multiple layers, the surface of the shaped part is formed in a flat surface and the surface layer is formed to multilayer bristle planting layer 9 having a first bristle planting layer 26a and a second bristle planting layer 26b constituted by fixing the short fiber on the surface of the first bristle planting layer 26a.
