Disclosed is an electromagnetic type delay line comprising an inductance element formed of a coiled conductor and a plurality of capacitors connecting the conductor to ground and consequently possessing a plurality of sections. The inductance element is formed by coiling the conductor at a prescribed pitch in the shape of a single-layer solenoid. In the inductance element, the one-turn pitch P and half-turn pitch B are selected so as to satisfy the expression, B/P>/=1.0. Owing to this construction, the coupling coefficients between the individual sections of the inductance element can be easily approximated to the theoretically optimum values.
