A flexible wiring cable includes a first wiring assembly connected to a load, a second wiring assembly connected to the first wiring assembly and extending toward an external signal source, and a circuit element mounted on the first wiring assembly to drive the load. The second wiring assembly is connected to the first wiring assembly at a position between the mounted circuit element and a connection point with the load. Thus, the heat of the circuit element is also transferred to the second wiring assembly, so that the effect of the heat on the load is reduced.
