NOVELTY - The wire harness (9) has a coaxial conducting wire (15) that is provided with several high voltage conducting paths (18,20) that are coaxially aligned. A covering segment (16) accommodates the coaxial conducting wire. The coaxial conducting wire is provided with a shield segment that is formed by metal and is coaxial to and arranged outside several high voltage paths. The covering segment is formed from a metal tubular segment that covers the coaxial conducting wire or a resin tubular segment that covers the coaxial conducting wire.    USE - Wire harness such as high voltage wire harness used for electrically connecting devices such as battery, motor unit and inverter unit of automobile such as hybrid automobile including hybrid vehicle or pure electric vehicle, or common automobile.    ADVANTAGE - The diameter of the conducting wire can be reduced by coaxially arranging several conducting paths, so that the diameter of the covering member that accommodates the conducting wire can also be reduced. The wire harness can be routed at a larger distance from the ground when the wire harness is routed on the under floor portion of the automobile. The coaxial conducting wire and the covering segment can exhibit the shielding function. The function of protecting the coaxial conducting wire can be enhanced, when the covering segment is formed as a metal tubular segment. The weight of the covering segment can be reduced while necessary and sufficient strength can be assured when the covering segment is formed as a resin tubular segment. The flexibility of the conducting wire can be reduced, and terminal work can be facilitated. The terminal can be coaxially connected to the outside path of the high voltage paths in coaxial conducting wire, and the coupling structure of the terminal for an outside circuit with respect to the outside circuit can be minimized.
