CABLE

WIPO Patent Application WO/2011/078190

A1

Disclosed is a cable capable of suppressing impedance mismatching caused by bending and twisting, while decreasing the dielectric constant between the inner conductor and outer conductor. A co-axial cable (1) is provided with an internal conductor (10), an insulating member (20) covering the outer circumference of the internal conductor (10), and an external conductor (30) covering the outer circumference of the insulating member (20). The insulating member (20) is characterized by having a resin braid (21) woven from multiple insulating resin fibers (22). By means of such a configuration, gaps are formed between neighboring resin fibers (22) and between the internal conductor (10) and the resin fibers (22), which makes it possible to decrease the dielectric constant between the internal conductor (10) and the external conductor (30). Further, because variation in the relative positions of the resin fibers (22) and variation in the size of the gaps between the resin fibers (22) can be suppressed, fluctuation of the dielectric constant between the internal conductor (10) and the external conductor (30), and impedance mismatching in the coaxial cable (1), can also be suppressed.
