Abstract
A composite cable is composed of a twisted pair formed by twisting together one pair of first electric wires each including a first conductor and a first insulation covering an outer circumference of the first conductor, one pair of second electric wires each including a second conductor greater in cross sectional area than the first conductor and a second insulation covering an outer circumference of that second conductor, the second electric wire being greater in outer diameter than the first electric wire, and a sheath covering aggregates together formed by stranding together the twisted pair and the one pair of second electric wires. The first conductors are formed by stranding a plurality of metal wires together. The second conductors are formed by stranding a plurality of aggregated strands together formed by stranding a plurality of metal wires together.
