摘要：
Provided is a leaky coaxial cable in which a plurality of slots 1 for forming a leak electromagnetic field are arranged in a string shape in an outer conductor of the coaxial cable. The pitch interval of the slots 1 is periodically changed in the axial direction. The periodical change of the pitch interval of a slot portion changes according to a sinusoidal function, a quadratic function, or other functions.
