In the present invention, a wire harness 1 comprises an electrical wire 11, a bundling tie 20 that is wound around and fixed to the electrical wire 11, and a housing 30 that sheathes the electrical wire 11. The housing 30 has a restrictive groove 46 that receives the bundling tie 20. Displacement of the electrical wire 11 with respect to the housing 30 is restricted by the bundling tie 20 being locked by a groove side surface 46A of the restrictive groove 46. Due to this configuration, manufacturing tolerance and assembly tolerance can be accommodated by setting a fixed clearance between the bundling tie 20 and the groove side surface 46A. In addition, even in the case where a tensile force acts on the electrical wire 11, shifting of the winding position of the bundling tie 20 with respect to the electrical wire 11 can be suppressed.
