Zusammenfassung:To provide a shielding material having high bending resistance and capable of maintaining a high noise shielding effect even when subjected to repeated bending, and a communication wire provided with such a shielding material.SOLUTION: A shielding material 4 has a braided body 41 in which a plurality of metal element wires 41a are woven, and a shielding aid 42 having fluidity and containing a conductive material and arranged in contact with the braided body 41. A communication wire has a core wire having a conductor and an insulating layer coating the outer circumference of the conductor, and the shielding material 4 coating the outer circumference of the core wire.SELECTED DRAWING: Figure 2 【課題】高い耐屈曲性を有し、繰り返して屈曲を受けても、高いノイズ遮蔽効果を維持することができるシールド材、およびそのようなシールド材を備えた通信用電線を提供する。【解決手段】複数の金属素線41aを編み込んだ編組体41と、流動性を有し、かつ導電性材料を含み、前記編組体41に接触して配置されたシールド補助剤42と、を有するシールド材4とする。また、導体と、前記導体の外周を被覆する絶縁層と、を有するコア線と、前記コア線の外周を被覆する前記シールド材4と、を有する通信用電線とする。【選択図】図2
