Summary:PROBLEM TO BE SOLVED: To provide a communication wire whose diameter is made smaller while ensuring a characteristic impedance value having necessary magnitude.SOLUTION: There is provided a communication wire 1 comprising: a pair of insulated wires 11 including a conductor 12 having a tensile strength of 400 MPa or more and an insulated coating 13 covering an outer periphery of the conductor 12; a twisted-pair wire 10 obtained by twisting together the pair of the insulated wires 11; and a sheath 30 made of an insulated material that covers the outer periphery of the twisted-pair wire 10. There is an air gap G between the sheath 30 and the insulated wire 11 that configures the twisted-pair wire 10. The communication wire has a characteristic impedance in the range of 100±10 Ω.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】引張強さが４００ＭＰａ以上である導体１２と、該導体１２の外周を被覆する絶縁被覆１３と、からなる１対の絶縁電線１１，１１が撚り合わせられた対撚線１０と、対撚線１０の外周を被覆する絶縁材料よりなるシース３０と、を有し、シース３０と対撚線１０を構成する絶縁電線１１との間に、空隙Ｇが存在し、特性インピーダンスが、１００±１０Ωの範囲にある通信用電線１とする。【選択図】図１
