Summary:To provide a communication wire which is hardly disengaged from a fixture and has transmission characteristics designed for high speed communication.SOLUTION: A communication wire 1A has a twisted pair cable 2 formed by twisting insulated wires 11A and 11B, and a sheath 12A which covers the outer periphery of the twisted pair cable 2 and is formed of a polyolefin-based resin. The insulated wires 11A and 11B include core wires 111 formed by twisting element wires 1111, and insulation coatings 112 which are formed of a polyolefin-based resin. The communication wire 1A has a characteristic impedance within a range of 100 Ω±10 Ω, and the outer diameter of the sheath 12A is less than 2.4 mm.SELECTED DRAWING: Figure 1 【課題】固定具から外れにくく高速通信に対応した伝送特性を有する通信用電線を提供する。【解決手段】通信用電線1Aは、絶縁電線11A、11Bを対撚りした対撚り線2と、対撚り線2外周を覆うポリオレフィン系樹脂で形成されたシース12Aと、を有する。絶縁電線11A、11Bは、素線1111を撚った撚線であるコア線111と、ポリオレフィン系樹脂で形成された絶縁被覆112と、を有する。通信用電線1Aは、特性インピーダンスが100Ω±10Ωの範囲内であり、シース12Aの外径が2.4mm未満である。【選択図】図1
