Abstract
A nonreciprocal circuit element including a ferrite assembly which ha a pair of ferrite members and a plurality of central conductors interposed between the ferrite members, and a dielectric substrate which has an earthing electrode formed on one of its faces and a plurality of impedance matching electrodes formed on the other face, and wherein a direct current magnetic field is applied to the ferrite members. The ferrite assembly and the dielectric substrate are stacked such that lead-out portions of the central conductors are, respectively, connected to the impedance matching electrodes, while earthing portions of the central conductors and the earthing electrode are grounded.
