ABSTRACT:
In the disclosed nonreciprocal circuit device, which employs a single-board-type capacitor, the problem of electrode peeling can be avoided. The nonreciprocal circuit device has characteristics such that attenuation is small in the direction of signal transmission and attenuation is large in the reverse direction and has matching capacitors disposed in signal input/output ports. The matching capacitors are formed of single-board-type capacitors including capacitor electrodes formed so as to be opposed each other on both main surfaces of a dielectric substrate with the substrate in between. An outer peripheral edge of a grounding electrode (or another connected electrode), to which a capacitor electrode of the single-board-type capacitor is connected, is positioned inwardly from an outer peripheral edge of the capacitor electrode.
