摘要： PROBLEM TO BE SOLVED: To reduce a manufacturing cost in a method for manufacturing a leaky cable. SOLUTION: The method for manufacturing the leaky cable 30 including a slot for radiating and entering electromagnetic waves includes: a step of forming a first cable base material 10 comprising a first external conductor base material 12, a first insulating base material 14 and an inner conductor 16; a step of forming a second cable base material 11 comprising a second external conductor base material 22 on which a slot 20 is formed and a second insulating base material 24; a step of superposing the first cable base material 10 on the second cable base material 11, so that the inner conductor 16 is held and enclosed between the first insulating base material 14 and the second insulating base material 24 to form an insulator; and a step of connecting the first external conductor base material 12 to the second external conductor base material 22 so as to enclose the insulator to form an external conductor.

摘要： The present invention includes: an inner conductor (10) which extends in the axial direction and in which a signal propagates; an insulator (12) covering the inner conductor (10); a first outer conductor (14) where a conductor wire is placed on an outer circumferential surface of the insulator (12) at a shielding density by which part of the signal leaks outside; and a plurality of second outer conductors (16) that are placed at a constant pitch in the axial direction in contact with the first outer conductor (14) to block the signal. In the axial direction, the electrical length of each of the plurality of second outer conductors (16) is the same as the electrical length between the adjacent second outer conductors, and, when the wavelength shortening rate with respect to the free space wavelength of the propagation wavelength of the signal is nu, the pitch is within the range of between {1/(1+0.766nu)} times and {3/(1+nu)} times the propagation wavelength.
