The cable routing device serves for routing at least one cable of a moved machine part in the manner of a drag chain. The cable routing device is bendable in a reversible manner in at least one defined bending direction and to this end has a flexurally flexible carrier structure, which extends in a longitudinal direction. Embedded into said carrier structure is an insert part with a cross sectional geometry different from circular. The bending direction is determined by the cross sectional geometry of the insert part. The cable routing device, in this case, is realized in the longitudinal direction from a plastic compound by a continuous shaping operation, wherein the insert part is at the same time incorporated into the carrier structure. The cable routing device has cross sectional geometries that vary in the longitudinal direction and are formed by the continuous shaping operation.
