Abstract

A flat cable includes a plurality of coaxial cables mutually arranged in parallel, wherein in the coaxial cable, a cross-sectional area of a central conductor is 0.006 mm2 or less, and an insulating film having a base material, and a thermoplastic adhesive layer formed on the base material. The insulating film is stuck on only one side of a parallel plane of the plurality of coaxial cables, and the plural coaxial cables are fixed to the thermoplastic adhesive layer.

Description

Technical field [0001] The invention relates to a flat cable with a coaxial cable. Background technique [0002] There are cases where the flat cable must be bent and routed according to the routing path of the flat cable. Generally, FPC (Flexible Printed Circuit Board) is used to perform wiring, but in the case of transmitting high-speed electrical signals, there are limitations on communication speed or distance. As a solution, you can consider using coaxial cables with good high-speed transmission performance. For example, in Patent Document 1, in order to bundle each coaxial cable constituting a flat cable, first, a plurality of coaxial cables are arranged in the same plane, and a flexible adhesive is applied near the center of the coaxial cable and cured . Then, fold the ends of each coaxial cable, fix the folded part with tape, and form the desired folded part.
