Vehicle composite cable and vehicle composite harness

A vehicle composite cable, comprising:

• a pair of power wires for supplying a current to an electric parking brake unit that generates a braking force after stopping a vehicle;
• a first signal line comprising a twisted pair wire transmitting a first electrical signal during when the vehicle is in motion;
• a second signal line comprising a twisted pair wire for transmitting a second electrical signal also during when the vehicle is in motion;
• and
• a sheath collectively covering the pair of power wires and the first and second signal lines,
• wherein the first and second signal lines are not covered with a shield conductor, and the first signal line is separated from the second signal line by the pair of power wires, and wherein the sheath includes an artificial polypeptide fiber.
