To provide a communication wire that has a reduced diameter while ensuring the characteristic impedance value of the required size.SOLUTION: A communication wire 1 has a twisted pair wire 10 obtained by twisting together a pair of insulation wires 11,11, each insulation wire comprising a conductor 12 and an insulation coating 13 covering the outer circumference of the conductor 12 and having a conductor cross-sectional area of less than 0.22 mm2. The communication wire 1 has a characteristic impedance in the range of 100 ± 10 Ω. The conductor 12 is a twisted wire containing an element wire having a predetermined alloy composition, and the break elongation of it is 7% or more.SELECTED DRAWING: Figure 1 【課題】必要な大きさの特性インピーダンス値を確保しながら、細径化された通信用電線を提供すること。【解決手段】導体１２と、該導体１２の外周を被覆する絶縁被覆１３と、からなり、導体断面積が０．２２ｍｍ２未満である絶縁電線１１，１１が１対撚り合わせられた対撚線１０を有し、特性インピーダンスが、１００±１０Ωの範囲にあり、導体１２は、所定の合金組成を有する素線を含む撚線であり、破断伸びが７％以上であるである通信用電線１とする。【選択図】図１
