Abstract: The present invention is to provide an apparatus for coloring an electrical wire to improve a visibility and design of the electrical wire. The apparatus includes a coloring device for ejecting a liquid coloring material to an outer surface of the electrical wire and a sliding device for moving relatively the coloring device in a direction perpendicular to a longitudinal direction of the electrical wire so as to color each whole outer surface of a plurality of coloring regions thereof responsive to a belt-shaped design pattern.

Abstract: A wiring harness 1 includes: an electric wire 2; and a connector 3. The electric wire 2 includes: a conductive core wire 21; and an insulating cover 22 for covering the core wire 21. The connector 3 is attached to an end 2a of the electric wire 2, and receives the end 2a of the electric wire 2. A first marker 6 and a second marker 7 are formed on an outer surface 22a of the cover 22 of the electric wire 2. The first marker 6 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 received in the connector 3 in a color A. The second marker 7 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 exposed to an outside of the connector 3.

Abstract: To provide a wiring harness of which electric wire is surely distinguishable by preventing a marker formed on an outer surface of a cover of the electric wire from at least partially being removed. A wiring harness 1 includes: an electric wire 2; and a connector 3. The electric wire 2 includes: a conductive core wire 21; and an insulating cover 22 for covering the core wire 21. The connector 3 is attached to an end 2a of the electric wire 2, and receives the end 2a of the electric wire 2. A first marker 6 and a second marker 7 are formed on an outer surface 22a of the cover 22 of the electric wire 2. The first marker 6 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 received in the connector 3 in a color A different from a mono color N of the outer surface 22a. The second marker 7 is formed by coloring a part of the outer surface 22a of the cover 22 of the electric wire 2 exposed to an outside of the connector 3 in the color A the same as the first marker 6.
