Summary:PROBLEM TO BE SOLVED: To provide a communication wire reduced in its diameter, while securing a required characteristic impedance value.SOLUTION: Provided is a communication wire 1 which includes a paired twisted wire 10 in which a pair of insulated wires 11, 11, each formed with a conductor 12 whose tensile strength is 400 MPa or more and an insulation coating 13 that covers the outer periphery of the conductor 12, are twisted. The characteristic impedance is within a range of 100±10 Ω, and a difference between the electrostatic capacitances of the insulated wires constituting the paired twisted wire 10 is 25 pF/m or less.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を有し、特性インピーダンスが、１００±１０Ωの範囲にあり、対撚線１０を構成する絶縁電線の静電容量の差が、２５ｐＦ／ｍ以下である通信用電線１とする。【選択図】図１
