To provide a conveying belt not loosened even if the contact lengths of the belt on pulleys are different from each other by reducing the coefficient of friction on the conveying surface thereof and sustaining the reduced effect for long period in the carrying belt formed by applying flat belts between multiple shafts.

In this conveying belt, the rear faces of the flat belts A and B are fitted to each other, and a product is held between the belts to convey the product by utilizing the frictional force thereof with the product. The conveying surface is formed of a single or a plurality of elastomer members, anti-friction material is mixed with the elastomer member at least in the outermost layer of the elastomer member, and a part of the anti-friction material is exposed to the surface.
