Method of manufacturing an automobile high voltage wire harness

1. A method of manufacturing an automobile high voltage wire harness comprising:

setting a shrinkable tube which has a color to make the wire harness recognized as a high voltage one outside a metal pipe body which is an exterior member of one or a plurality of high voltage electrical pathway(s) wired in an automobile;

making the shrinkable tube shrink to cover part of or all of the outer surface of the metal pipe body; and

bending the metal pipe body to a predetermined position to be formed into a three-dimensional shape.

2. A method of manufacturing an automobile high voltage wire harness comprising:

inserting a metal pipe body, which is an exterior member of one or a plurality of high voltage electrical pathway(s) wired in an automobile, into a shrinkable tube;

setting the metal pipe body and the shrinkable tube at a predetermined position, wherein the shrinkable tube covers part of or all of an outer surface of the metal pipe body, and at least one end portion of the shrinkable tube is longer than a respective at least one end portion of the metal pipe body by a predetermined length;

inserting the predetermined length of the at least one end portion of the shrinkable tube into a respective inside of the at least one end portion of the metal pipe body such that a surface of the at least one end portion of the metal pipe body is covered by the at least one shrinkable tube end portion; and

bending the metal pipe body to a predetermined position to be formed into a three-dimensional shape,

wherein the shrinkable tube has a color to make the wire harness recognized as a high voltage one outside the metal pipe body.

3. The method of manufacturing the automobile high voltage wire harness according to claim 2 , further comprising:

folding back ends of the shrinkable tube in order to insert the at least one end portion of the shrinkable tube into the inside of the metal pipe body.
