A high voltage wire harness for use in an automobile comprising: one or a plurality of high voltage conductive paths routed in an automobile; and a metallic tubular body made of aluminum adapted to serve as an exterior cladding member for the high voltage conductive paths, a high voltage recognition component capable of letting a worker recognize that the wire harness includes a high voltage characterized in that the high voltage recognition component (17b,17c) is retrofitted to an exterior surface side of the metallic tubular body and includes a configuration of either of the following (i) or (ii): (i) the high voltage recognition component has C-shaped tubular portions (27 and 28) that form installation openings and a hinge that connects the C-shaped tubular portions (27 and 28) to each other, and the high voltage recognition component is formed by extrusion molding of an orange-colored resin and cutting the thus-molded article to a predetermined length in such a shape as to assume a tubular shape and cause an overlap when installed on the metallic tubular body: (ii) the high voltage recognition component has C-shaped tubular portions (32 and 33) that are to form installation openings and a hinge that connects the C-shaped tubular portions (32 and 33) to each other, and the high voltage recognition component is made of orange-colored resin and is formed into such a shape as to form a corrugated tube and cause an overlap when installed on the metallic tubular body. one or a plurality of high voltage conductive paths routed in an automobile; and a metallic tubular body made of aluminum adapted to serve as an exterior cladding member for the high voltage conductive paths, a high voltage recognition component capable of letting a worker recognize that the wire harness includes a high voltage characterized in that the high voltage recognition component (17b,17c) is retrofitted to an exterior surface side of the metallic tubular body and includes a configuration of either of the following (i) or (ii): (i) the high voltage recognition component has C-shaped tubular portions (27 and 28) that form installation openings and a hinge that connects the C-shaped tubular portions (27 and 28) to each other, and the high voltage recognition component is formed by extrusion molding of an orange-colored resin and cutting the thus-molded article to a predetermined length in such a shape as to assume a tubular shape and cause an overlap when installed on the metallic tubular body: (ii) the high voltage recognition component has C-shaped tubular portions (32 and 33) that are to form installation openings and a hinge that connects the C-shaped tubular portions (32 and 33) to each other, and the high voltage recognition component is made of orange-colored resin and is formed into such a shape as to form a corrugated tube and cause an overlap when installed on the metallic tubular body.
