Abstract
A nonreciprocal circuit device includes a ferrite to which a direct magnetic field is applied using permanent magnets, central electrodes arranged on the ferrite, and a circuit substrate. The first central electrode is made of conductive films, and the second central electrode is made of conductive films. Some of the conductive films of the second central electrode are arranged on the first main surface of the ferrite, and a conductive film of the first central electrode is arranged on the conductive films through an insulating film. Furthermore, another one of the conductive films of the first central electrode is arranged on the second main surface, and the remainder of the conductive films of the second central electrode are arranged through an insulating film on the conductive film.
