Moreover, the shield member can suppress the influence of electromagnetic waves generated from the high voltage line from reaching the low voltage line.

（ワイヤハーネスＷの製造方法）
　ワイヤハーネスＷは、例えば以下のように製造される。まず、金属製の筒体の内周と外周に絶縁塗装がなされて、導電パイプ２０が形成される（図２参照）。電線１０の外周は、シールド部材３０で覆われる。電線１０は、シールド部材３０で覆われた状態で、導電パイプ２０内に通される（図２参照）。第１継ぎ足し電線４０の第１接続部４３は、第１固定部材４４によって、導電パイプ２０の第１露出面２４に接触した状態で固定される（図３参照）。第２継ぎ足し電線５０の第２接続部５３は、第２固定部材５４によって、導電パイプ２０の第２露出面２５に接触した状態で固定される（図３参照）。 (Method for manufacturing wire harness W)

First, an insulating coating is applied to the inner and outer peripheries of a metal cylinder to form the conductive pipe 20 (see FIG. 2). The outer periphery of the electric wire 10 is covered with a shield member 30. The electric wire 10 is passed through the conductive pipe 20 while being covered with the shield member 30 (see FIG. 2).

（ワイヤハーネスＷの作用）
　ワイヤハーネスＷは、電線１０を高圧線として利用し、電線１０の外周を覆う導電パイプ２０を低圧線として利用することができる。このため、構造の簡易化を図りつつ、高圧線と低圧線を並走させることができる。更に、電線１０と導電パイプ２０との間には、シールド部材３０が介在しており、電線１０の外周は、シールド部材３０によって覆われている。このため、シールド部材３０によって、高圧線から生じた電磁波の影響が低圧線に及ぶことを抑制するとともに、ワイヤハーネスＷの外部に漏れることを抑制することができる。また、導電パイプ２０によって構成される低圧線の強度を高めることができるとともに、導電パイプ２０によって、内部に配置された電線１０を保護することができる。 (Function of wire harness W)
The wire harness W can use the electric wire 10 as a high-voltage line, and use the conductive pipe 20 covering the outer periphery of the electric wire 10 as a low-voltage line. Therefore, the high voltage line and the low voltage line can be made to run in parallel while simplifying the structure. Further, a shield member 30 is interposed between the electric wire 10 and the conductive pipe 20, and the outer periphery of the electric wire 10 is covered with the shield member 30. Therefore, the shield member 30 can suppress the influence of electromagnetic waves generated from the high voltage line from reaching the low voltage line, and can also suppress leakage to the outside of the wire harness W. Further, the strength of the low voltage line constituted by the conductive pipe 20 can be increased, and the electric wire 10 disposed inside can be protected by the conductive pipe 20.
　更に、導電パイプ２０は、筒状の導電層２１と、導電層２１の内周を覆う筒状の内側絶縁層２２と、を有している。このため、導電パイプ２０の導電層２１がシールド部材３０に接触することを回避できる。 Further, the conductive pipe 20 includes a cylindrical conductive layer 21 and a cylindrical inner insulating layer 22 that covers the inner circumference of the conductive layer 21. Therefore, the conductive layer 21 of the conductive pipe 20 can be prevented from contacting the shield member 30.
　更に、導電パイプ２０は、導電層２１の外周を覆う筒状の外側絶縁層２３を有している。このため、導電パイプ２０の導電層２１が外部の導体に接触することを回避できる。 Further, the conductive pipe 20 has a cylindrical outer insulating layer 23 that covers the outer periphery of the conductive layer 21. Therefore, it is possible to prevent the conductive layer 21 of the conductive pipe 20 from coming into contact with an external conductor.
　更に、導電層２１の外周面は、導電パイプ２０の長さ方向の一方側の端部に外側絶縁層２３から露出した第１露出面２４と、他方側の端部に外側絶縁層２３から露出した第２露出面２５と、を有している。ワイヤハーネスＷは、第１露出面２４に電気的に接続される第１継ぎ足し電線４０と、第２露出面２５に電気的に接続される第２継ぎ足し電線５０と、を備えている。第１継ぎ足し電線４０及び第２継ぎ足し電線５０は、いずれも可撓性を有している。この構成によれば、導電パイプ２０によって剛性の高い導電路を構成することができ、第１継ぎ足し電線４０及び第２継ぎ足し電線５０によって撓みやすい導電路を構成することができる。また、第１継ぎ足し電線４０及び第２継ぎ足し電線５０が導電層２１の外周面に接続されるため、第１継ぎ足し電線４０及び第２継ぎ足し電線５０がシールド部材３０に接触することを回避できる。 Further, the outer peripheral surface of the conductive layer 21 includes a first exposed surface 24 exposed from the outer insulating layer 23 at one end of the conductive pipe 20 in the length direction, and a first exposed surface 24 exposed from the outer insulating layer 23 at the other end. It has a second exposed surface 25. The wire harness W includes a first supplementary electric wire 40 electrically connected to the first exposed surface 24 and a second supplementary electric wire 50 electrically connected to the second exposed surface 25. Both the first additional electric wire 40 and the second additional electric wire 50 have flexibility. According to this configuration, a highly rigid conductive path can be configured by the conductive pipe 20, and a flexible conductive path can be configured by the first supplementary electric wire 40 and the second supplementary electric wire 50. Further, since the first supplementary electric wire 40 and the second supplementary electric wire 50 are connected to the outer peripheral surface of the conductive layer 21, it is possible to avoid the first supplementary electric wire 40 and the second supplementary electric wire 50 from coming into contact with the shield member 30.
　更に、ワイヤハーネスＷは、導電パイプ２０の一方側の開口から出た電線１０と第１継ぎ足し電線４０とを内部に配置させる筒状の第１外装部材６０と、他方側の開口から出た電線１０と第２継ぎ足し電線５０とを内部に配置させる筒状の第２外装部材７０と、を備えている。第１外装部材６０及び第２外装部材７０は、いずれも可撓性を有している。この構成によれば、導電パイプ２０の一方側の開口から出た電線１０と第１継ぎ足し電線４０を第１外装部材６０の内部でまとめて配置させることができ、他方側の開口から出た電線１０と第２継ぎ足し電線５０を第２外装部材７０の内部でまとめて配置させることができる。しかも、導電パイプ２０の一方側の開口から出た電線１０と第１継ぎ足し電線４０を第１外装部材６０とともに曲げやすく、他方側の開口から出た電線１０と第２継ぎ足し電線５０を第２外装部材７０とともに曲げやすい。 Furthermore, the wire harness W includes a cylindrical first exterior member 60 in which the electric wire 10 and the first supplementary electric wire 40 that come out from an opening on one side of the conductive pipe 20 are disposed, and an electric wire that comes out from an opening on the other side. 10 and a cylindrical second exterior member 70 in which the second additional electric wire 50 is disposed. Both the first exterior member 60 and the second exterior member 70 have flexibility. According to this configuration, the electric wire 10 coming out of the opening on one side of the conductive pipe 20 and the first additional electric wire 40 can be arranged together inside the first exterior member 60, and the electric wire coming out from the opening on the other side 10 and the second additional electric wire 50 can be arranged together inside the second exterior member 70. Moreover, the electric wire 10 and the first supplementary electric wire 40 coming out from the opening on one side of the conductive pipe 20 are easily bent together with the first exterior member 60, and the electric wire 10 and the second supplementary electric wire 50 coming out from the opening on the other side can be easily bent with the second exterior member 60. It is easy to bend together with the member 70.
　更に、ワイヤハーネスＷは、導電パイプ２０の外側絶縁層２３と第１外装部材６０との端部同士をつなぎ、第１露出面２４に対する第１継ぎ足し電線４０の第１接続部４３を覆う筒状の第１防水部材６１を備えている。この構成によれば、第１露出面２４に対する第１継ぎ足し電線４０の第１接続部４３を、第１防水部材６１によって防水することができる。また、ワイヤハーネスＷは、導電パイプ２０の外側絶縁層２３と第２外装部材７０との端部同士をつなぎ、第２露出面２５に対する第２継ぎ足し電線５０の第２接続部５３を覆う筒状の第２防水部材７１を備えている。この構成によれば、第２露出面２５に対する第２継ぎ足し電線５０の第２接続部５３を、第２防水部材７１によって防水することができる。 Furthermore, the wire harness W has a cylindrical shape that connects the ends of the outer insulating layer 23 of the conductive pipe 20 and the first exterior member 60, and covers the first connecting portion 43 of the first supplementary wire 40 to the first exposed surface 24. The first waterproof member 61 is provided. According to this configuration, the first connection portion 43 of the first additional electric wire 40 to the first exposed surface 24 can be waterproofed by the first waterproof member 61. The wire harness W also has a cylindrical shape that connects the ends of the outer insulating layer 23 of the conductive pipe 20 and the second exterior member 70 and covers the second connecting portion 53 of the second additional electric wire 50 to the second exposed surface 25. The second waterproof member 71 is provided. According to this configuration, the second connection portion 53 of the second supplementary electric wire 50 to the second exposed surface 25 can be waterproofed by the second waterproof member 71.
　更に、外側絶縁層２３は、高圧線が配策されていることを示す色に着色されている。このため、導電層２１の外周を覆う外側絶縁層２３の色によって、高圧線が配策されていることを示すことができる。 Further, the outer insulating layer 23 is colored to indicate that a high voltage line is installed therein. Therefore, the color of the outer insulating layer 23 covering the outer periphery of the conductive layer 21 can indicate that a high voltage line is installed.
　＜実施形態２＞
