As a result, the corrugated tube 12 that is slackened when the slide door 2 is slid has the side portion 31b having a lower rigidity than the side portion 31a having a higher rigidity in the bending direction regulation region K as shown in FIG. 1 (b). It will be bent in the predetermined direction C inside.

  Thus, according to the wire harness 11 according to the present embodiment, the corrugated tube 12 is provided with the bending direction regulation region K in which the rigidity of the side portion 31a that is the outer side of the bending is increased in the middle portion thereof. Thus, when the sliding door 2 is slid, the sliding door 2 is reliably bent in the predetermined direction C. Thereby, when the slide door 2 slides, the corrugated tube 12 bends in an unintended direction and can be reliably prevented from being damaged by contacting the vehicle body 1 or the slide door 2. Further, compared with a structure in which a spring or the like for bending in the predetermined direction C when the sliding door 2 slides, the number of parts can be reduced and the structure can be simplified, and the cost can be reduced.

  In addition, by providing the plate-like portion 32 along the longitudinal direction on one side portion 31a of the corrugated tube 12, the rigidity of the one side portion 31a can be easily increased and easily bent in the predetermined direction C.
