Method for manufacturing a cable harness and wiring harness

Abstract

A method for manufacturing a cable harness, comprising: a method for accommodating a plurality of electrical wires (3) in a slot section (110) of a device plate (100) having the slot section; and a method for forming a trunk wire section in which the plurality of electrical wires is bundled by attaching a plurality of first bundling elements (4) to the plurality of electrical wires accommodated in the slot section, wherein in the method for forming the trunk wire section the first bundling elements are attached to the plurality of electrical wires in each of a plurality of through holes (140) formed at a distance in the slot section, and one of the first bundling elements is encircled around the plurality of electrical wires at the same position in one extension direction of the electrical wires.
