1. A composite cable, comprising:
plural electric power wires;
a first twisted wire made by laying plural signal wires together;
a second twisted wire disposed opposite the first twisted wire with the electric power wires between the first twisted wire and the second twisted wire, the second twisted wire being made by laying plural grounding wires having a cross-sectional area smaller than that of the plural electric power wires; and
a sheath formed over plural electric power wires, the first twisted wire, and the second twisted wire,
wherein each of the plural grounding wires of the second twisted wire is composed of a conductor and an insulator formed over the conductor.
