PROBLEM TO BE SOLVED: To provide an electric wire which increases the degree of freedom of a routing path, reduces a routing space and allows efficient routing work.SOLUTION: An electric wire comprises an inner conductor 11 consisting of a plurality of single wires W bundled, an inner insulation layer 12 covering the surrounding of the inner conductor 11, an outer conductor 13 which is arranged along the outer periphery of the inner insulation layer 12 and consists of a plurality of single wires W and an outer insulation layer 14 covering the surrounding of the outer conductor 13. The single wires W constituting the inner conductor 11 are twisted spirally; the single wires W constituting the outer conductor 13 are twisted spirally; and the outer conductor 13 has a larger twisting pitch L2 than that of the inner conductor 11. 【課題】配索経路の自由度を高め配索スペースの縮小化を図るとともに配索作業を効率化することができる電線を提供する。【解決手段】複数の単線Ｗをまとめた内側導体１１と、内側導体１１の周囲を覆う内側絶縁層１２と、内側絶縁層１２の外周に沿う複数の単線Ｗからなる外側導体１３と、外側導体１３の周囲を覆う外側絶縁層１４と、を備え、内側導体１１を構成する複数の単線Ｗが螺旋状に撚り合わされるとともに、外側導体１３を構成する複数の単線Ｗが螺旋状に撚り合わされており、内側導体１１よりも大きな撚り合わせピッチＬ２を有して外側導体１３が構成されている。【選択図】図３
