To provide a cut-off electric wire which can cut-off water without performing a peeling-off work and has excellent cut-off performance.SOLUTION: A cut-off electric wire 1 includes a conductor 2 formed of a plurality of conductor element wires 21, an insulator 3 covering the conductor 2, a through hole 31 penetrating through the insulator 3, and a cut-off material 4 which fills inside of a hole of the through hole 31, a gap 30 between an outer surface of the conductor 2 and the insulator 3, and a gap 20 between the conductor element wires 21. The cut-off material 4 is formed of a thermosetting resin or thermosetting elastomer. The insulator 3 is formed of a thermoplastic resin.SELECTED DRAWING: Figure 1 【課題】皮剥ぎ加工を行うことなく止水でき、優れた止水性能を有する止水電線を提供する。【解決手段】止水電線１は、複数の導体素線２１からなる導体２と、導体２を被覆する絶縁体３と、絶縁体３を貫通する貫通孔３１と、貫通孔３１の孔内、導体２の外表面と絶縁体３との隙間３０及び導体素線２１間の隙間２０に充填された止水材４とを有している。止水材４は、熱硬化型樹脂または熱硬化型エラストマーからなる。絶縁体３は、熱可塑性樹脂からなる。【選択図】図１
