Wire harness exterior member and wire harness

1. A tube-shaped wire harness exterior member which houses and protects at least one conductive path, comprising:

wherein the wire harness exterior member is formed by connecting metal pipes made of different materials,

wherein at least one of the metal pipes is formed from aluminum, and the at least one of the metal pipes includes a bent portion,

wherein a metal material having corrosion resistance is used for at least a part of the wire harness exterior member, and

wherein each of the metal pipes spans a length and has a cross-sectional dimension that is substantially constant along the length.

2. The exterior member according to claim 1 ,

wherein the metal pipes are connected:

by welding;

by fastening flanges formed in the metal pipes to each other by a fastening member; or

using a coupling member.

3. A wire harness comprising:

the wire harness exterior member according to claim 1 ; and

at least one conductive path housed and protected by the wire harness exterior member.

4. The exterior member according to claim 1 , wherein another one of the metal pipes is formed from a metal material that is different from the aluminum of the at least one metal pipe.

5. The exterior member according to claim 1 , wherein another one of the metal pipes is formed from aluminum that is different from the aluminum of the at least one of the metal pipes.

6. The exterior member according to claim 1 , wherein the aluminum of the at least one of the metal pipes has shock resistance and strength.

7. The exterior member according to claim 1 , wherein another one of the metal pipes is formed of a metal material that is high in thermal conductivity.
