PROBLEM TO BE SOLVED: To make small the piping part and penetrating through part and execute an efficient work because wiring can be performed with one multi-conductor cable without two of the multi-conductor cable and an earthing conductor, by providing an earthing conductor composed of a conductor and an insulator fit to the allowable current of the multi-conductor cable in the center of the multi-conductor cable and integrating them. SOLUTION: In the center of a multi-conductor cable constituted of the conductors 3 of a cable, the insulators 4 of a cable, inclusion 6 such as paper or nylon, a retaining tape 5, and a sheath 7, the conductor 1 and the insulator 2 of an earthing conductor is put and they are integrated. For fitting to the allowable current of the multi- conductor cable, when the multi-conductor cable has three conductors of each 5.5 mm2, the conductor 1 of 2.2 mm2 of the earthing conductor is put in, and in the case of three conductors of each 22 mm2, the conductor 1 of 5.5 mm2 of the earthing conductor is put in. Consequently, it is unnecessary that only the earthing conductor is separately arranged afterward, the earthing conductor is put in and a part of inclusion is removed, and hence wiring can be performed with one multi-conductor cable. Hereby efficiency of the wiring work is improved, and refuse at processing a terminal end can be reduced.
