A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and embedded in the belt body. The belt tension T.sub.0.2 per 1 mm belt width at 0.2% of a belt extension rate is 70 N/mm or more. The belt tension T.sub.0.5 per 1 mm belt width at 0.5% of the belt extension rate is 220 N/mm or more. The ratio of the belt tension T.sub.0.2 to the belt tension T.sub.0.5 is 0.33 or more.

A transport, driving or pressing belt, comprising at least one belt material having a lower and an upper face limited by two longitudinal edges and two transverse edges running obliquely with respect to the main extension direction of the belt, the belt material being closed and the longitudinal edges being folded down, and a method for manufacturing a transport, driving or pressing belt. To ensure high tensile strength over the complete belt length and avoid an edge tearing of the first belt material at the longitudinal edges, the transverse edges of a first belt material lie against each other in abutting relationship, and a second belt material is arranged centrically on the first belt material at least in the region of the transverse edges. The second belt material here nearly covers a width of 50% of the first belt material and is centrically glued with the first belt material.
