An electromagnetic delay line of a distributed constant type making use of a zigzag strip as a strip line and suitable for use in very high frequency ranges. The zigzag strip comprises electroconductive strips which are bent in such a manner that they are arranged on a first imaginary plane and a second imaginary plane parallel and opposite thereto and spaced apart therefrom by an interval of T, in an alternating manner, and the pitch P and the interval T are so related to each other that the ratio T/P is greater than zero and smaller than unity. Therefore the coupling produced in the zigzag strip is enhanced and the enhanced positive coupling controls negative coupling by reducing or canceling it.
