PROBLEM TO BE SOLVED: To provide a leakage coaxial cable available in wide-band frequencies even under the condition where a diameter of an outer conductor is 0.12-fold as large as an input signal wavelength.SOLUTION: When a diameter of an outer conductor 4 is 0.12-fold as large as an input signal wavelength, a wavelength of an electromagnetic wave to be propagated in a length direction of a slot 6 in accordance with a specific dielectric constant of a jacket 5 is defined as λand a length of the slot is defined as 2L, on the assumption that a specific dielectric constant satisfying an expression (1) n×λ/2=2L (n=1, 2, 3...) ...(1) is defined as &egr;, as a jacket 5, a jacket having a specific dielectric constant &egr;is used which satisfies an expression (2) &egr;>&egr;×1.5 or &egr;<&egr;×0.5 ...(2). |
