    • An object of the present invention is to provide a high frequency cable which may, for example, be used in a high bandwidth of 70 GHz or more and has high heat resistance.A high frequency cable for a high bandwidth of 70 GHz or more, includes: one or a plurality of cable bodies, each of which includes a central conductor and a dielectric layer provided at an outer side of the central conductor; and an outer tube which is provided at an outer side of the cable body, in which the outer tube includes a first structure body in a helical shape and a second structure body in a helical shape, an inner diameter of the first structure body is smaller than that of the second structure body, the first structure body and the second structure body are mutually fitted in helical pitches, and each of the first structure body and the second structure body includes a material having a thermal conductivity of 9 W·m−1·K−1 or more, and in which in a bent state of the cable, a helix at an outer ring side of the second structure body is configured to move to an inner ring side of the second structure body so that the helix is fitted in a state of being embedded in a gap formed at an outer ring side of the first structure body and is contacted with the cable body.
