Composite cable and composite harness

A composite cable, comprising:

• a first twisted-pair wire formed by twisting a pair of first electric wires, the first electric wires each comprising a first center conductor and a first insulation covering the first center conductor;
• a second twisted-pair wire formed by twisting a pair of second electric wires, the second electric wires each comprising a second center conductor and a second insulation covering the second center conductor;
• a pair of third electric wires arranged between the first and second twisted-pair wires in a circumferential direction, the third electric wires each having a larger outer diameter than the first and second electric wires and comprising a third center conductor with a larger cross-sectional area than the first and second center conductors and a third insulation covering the third center conductor;
• and
• a tape member spirally wound around an assembled article that is formed by twisting the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires together,
• wherein the twisted-pair wires, the assembled article and the tape member are twisted or wound in a same direction.
