Abstract
A twinax cableincludes a twinax structure, the twinax structure including: a signal wire pair, the signal wire pair including a pair of signal wires formed of a first signal wire and a second signal wire, and an insulating layer configured to cover the pair of signal wires; a drain wire; and a shield tape arranged on the outer circumferential side of the insulating layer to cover the signal wire pair and the drain wire. The insulating layer is mainly composed of polyethylene. The insulating layer includes not less than 30 ppm and not more than 4000 ppm of a hindered phenol-based antioxidant. A dielectric tangent tan δ of the insulating layer at the time of application of a high-frequency electric field having a frequency of 10 GHz is not more than 3.0×10.
