To provide a multi-pair cable which can reduce an influence of cross talk.SOLUTION: A multi-pair cable includes an inner layer part obtained by twisting two cables for differential signal transmission for inner layer, a press-winding tape wound around the inner layer part, and an outer layer part formed by winding a plurality of cables for differential signal transmission for outer layer around the outer periphery of the press-winding tape, in which a cushioning tape is provided between the two cables for differential signal transmission for inner layer, the press-winding tape is spirally wound in a direction opposite to the twisting direction of the inner layer part and thereby the cushioning tape is held in an S shape, and the two cables for differential signal transmission for inner layer are arranged so as to be deviated in a long axis direction in cross-sectional view.SELECTED DRAWING: Figure 1 【課題】クロストークの影響を小さくすることが可能な多対ケーブルを提供する。【解決手段】２本の内層用の差動信号伝送用ケーブルを撚り合わせた内層部と、前記内層部の周囲に巻回された押え巻きテープと、複数の外層用の差動信号伝送用ケーブルを前記押え巻きテープの外周に巻回して形成される外層部と、を備えた多対ケーブルにおいて、前記２本の内層用の差動信号伝送用ケーブルの間に、緩衝テープが設けられ、前記押え巻きテープが、前記内層部の撚り方向とは逆方向に、螺旋状に巻き付けられることで、前記緩衝テープがＳ字状の形状で保持され、前記２本の内層用の差動信号伝送用ケーブルが断面視で長軸方向にずれて配置される。【選択図】図１
