WIRE HARNESS

A wire harness includes a conductor that flexibly connects a vehicle body side of a vehicle and a moving body that is mounted in the vehicle and slides with respect to the vehicle body, a regulation member that is configured by stacking a plurality of flexible plate members, extends along the conductor, and regulates a path of the conductor, and a pair of holding members that hold ends of the plurality of plate members. In the ends of the plurality of plate members, long holes are formed that extend along a longitudinal direction of the plate member at positions facing each other. The holding member includes a convex portion that is inserted in the long hole. The convex portion allows one plate member to relatively move along the longitudinal direction with respect to another plate member in a state where the convex portion is inserted in the long hole.
