PROBLEM TO BE SOLVED: To provide a shielded wire for communication which has a reduced diameter while ensuring a characteristic impedance value of the required magnitude.SOLUTION: A shielded wire for communication 1 has: a twisted pair wire 10 made by twisting together a pair of insulated wires 11, 11, each comprising a conductor 12 that has a tensile strength of 400 MPa or more and an insulating coating 13 with which the periphery of the conductor 12 is coated; and a shield 20 made of an electrically conductive material for enclosing the periphery of the twisted pair wire 10. The shielded wire for communication 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シールド電線を提供する。【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の外周を包囲する導電性材料よりなるシールド２０と、を有し、特性インピーダンスが、１００±１０Ωの範囲にある通信用シールド電線１とする。【選択図】図１
