Communication cable and manufacturing method thereof

The invention provides a communication cable corresponding to high-frequency data transmission and capable of simplifying the internal structure of the cable. Disclosed is a communication cable (1) in which a plurality of insulated wires (12), each of which is formed by covering a conductor (14) with an insulator (16), are twisted together. In a communication cable 1, a conductor 14 includes a single wire having a circular cross-section or a compressed stranded wire having a circular cross-section, and the ratio of the sum of the wire pitch of the compressed stranded wire to the arc length of the circumcircle of the compressed stranded wire is 71% or less. 本发明提供与高频数据传输对应且能够实现电缆的内部结构的简化的通信电缆。本发明公开了将多根由绝缘体16包覆导体14而成的绝缘电线12绞合而成的通信电缆1。在通信电缆1中，导体14包括剖面为圆形的单线或剖面为圆形的如下压缩绞线，该压缩绞线的线材间距的总和相对于该压缩绞线的外接圆的圆弧长度的比率为71％以下。
