PROBLEM TO BE SOLVED: To provide a coated electric wire intermediate material capable of improving cut-off performance at a desired position by simple working; a coated electric wire; a method for manufacturing a coated electric wire; and a wire harness.SOLUTION: A wire harness 10 includes a plurality of electric wires including a coated electric wire 20. The coated electric wire 20 has one cut-off portion 21, and is formed by working a coated electric wire intermediate material 30. The coated electric wire 30 has a plurality of element wires 31 and a coated portion 32 which has the plurality of element wires 31 stored therein, is formed of an insulative synthetic resin, and has a tube shape. The coated portion 32 is melted by partially heating and compressing the coated portion 32 in a longitudinal direction of the coated portion 32 from the periphery of the coated portion 32, and a part of the melted coated portion 32 penetrates a space S of the plurality of element wires 31.SELECTED DRAWING: Figure 3 【課題】本発明は、所望の位置で簡易な加工により止水性を向上させることができる被覆電線中間材、被覆電線、被覆電線の製造方法及びワイヤハーネスを提供する。【解決手段】ワイヤハーネス１０は、被覆電線２０を含む複数の電線を備えている。被覆電線２０は、１つの止水部２１を有し、被覆電線中間材３０を加工して形成されている。被覆電線３０は、複数の素線３１と、 複数の素線３１を内側に収容した絶縁性合成樹脂からなるチューブ形状の被覆部３２と、を有し、被覆部３２が、被覆部３２の周囲から被覆部３２の長手方向について部分的に加熱圧縮されることにより溶融されて、溶融された被覆部３２の一部が複数の素線３１の間隙Ｓに浸透するように構成されている。【選択図】図３
