PROBLEM TO BE SOLVED: To provide a leakage coaxial cable capable of suppressing a radiation wave at the terminal side.SOLUTION: A leakage coaxial cable 1 comprises: a linear central conductor 3 in which a signal propagates; an insulator 5 covering the central conductor 3; an external conductor 7 which covers the insulator 5 and has a plurality of slots 10 arranged along the axial direction of the central conductor 3 at a fixed pitch P; and a sheath 9 covering an outer periphery of the external conductor 7. The plurality of slots 10 are arranged so that its longitudinal direction is inclined by the same angleγto the axial direction. The pitch P is within a range of Aλg<P<λg, where a propagation wavelength of the signal isλg, a relative dielectric constant of the insulator isεr, and [(εr)/{1+(εr)}] is A. |
