WIRE HARNESS AND MANUFACTURING METHOD FOR WIRE HARNESS

To provide a wire harness in which liquid such as water does not permeate through a covering member and a wire harness manufacturing method. Further, improvement of the abrasion resistance of the covering member is aimed. A predetermined part of electric wires 91 is held or wrapped in a first material 801 and a second material 802 formed of a thermoplastic material, and a protective layer material 803 formed of a water repellent material is provided on approximately the entire surface of the first material and the second material. The first material 801, the second material 802 and the protective layer material 803 are heated and pressurized. The first material 801 and the second material 802 are molded to have a predetermined shape and size. The protective layer material 803 is joined to the surface of the first material and the second material 802 by melting at least a part of the surface layer of the first material 801 and the second material 802. Further, a material having high abrasion resistance is selected as the protective layer material 803.
