Communication cable and manufacturing method thereof

Provided is 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 obtained by covering a conductor (14) with an insulator (16), are twisted together. In a communication cable (1), an intervening cord (20) is interposed between insulated wires (12), and the insulated wires (12) are twisted at a pitch of 17.5 mm or less. 提供作为与高频数据传输相对应的通信电缆、且能实现电缆的内部结构的简化的通信电缆。公开了将用绝缘体(16)覆盖导体(14)而得的多根绝缘电线(12)绞合而得的通信电缆(1)。在通信电缆(1)中，介入绳(20)介于绝缘电线(12)之间，绝缘电线(12)以17.5mm以下的节距被绞合。
