PROBLEM TO BE SOLVED: To provide a method of producing a wire harness which enables production, through simple steps, of a wire harness capable of retaining a wiring shape of an exterior member with sufficient rigidity and a wire harness capable of retaining a wiring shape of an exterior member with sufficient rigidity.SOLUTION: A method of producing a wire harness X1 includes a step of preparing an exterior member 2 which is cylindrical and surrounds a hollow part 21 and has a shape consisting of a plurality of crest parts 22 and a plurality of trough parts 23, arranged alternately along the axial direction, so as to be capable of elastic bending deformation, a step of inserting a wire 1 into the hollow part 21 of the exterior member 2, a step of forming the wire 1 and the exterior member 2 into a specified wiring shape by bending deformation, a step of arranging a heat-shrinkable member 4 in such a way as to surround, in the circumferential direction of the exterior member 2, the outer peripheral surface of the exterior member 2 after the deformation into a specified wiring shape and a step of heating the heat-shrinkable member 4 to shrink in the radial direction of the exterior member 2 so as to come in contact with the outer peripheral surface of the exterior member 2 and thereby make the wiring shape of the exterior member 2 retained.
【課題】外装部材の配索形状を十分な剛性でもって保持することができるワイヤーハーネスを簡易な工程で製造する方法、および外装部材の配索形状を十分な剛性でもって保持することができるワイヤーハーネスを提供する。【解決手段】ワイヤーハーネスX1の製造方法は、中空部21を囲む筒状をなし、複数の山部22と複数の谷部23とが軸方向に沿って交互に並ぶ形状を有することにより弾性的に曲げ変形可能な外装部材2を準備する工程と、外装部材2の中空部21に電線1を挿入する工程と、電線1および外装部材2を曲げ変形させることにより所定の配索形状にする工程と、所定の配索形状に変形させた外装部材2の外周面を外装部材2の周方向に取り囲むように熱収縮部材4を配置する工程と、熱収縮部材4を加熱することで外装部材2の外周面に接するように外装部材2の径方向に収縮させ、これにより外装部材2の配索形状を保持させる工程と、を備える。【選択図】図2
