Zusammenfassung:A band pass filter circuit includes an input terminal, an output terminal, a signal line, and a plurality of main LC parallel resonators. First ends of the plurality of main LC parallel resonators are connected to the signal line, and second ends of the plurality of main LC parallel resonators are connected to one another. At least one attenuation-pole-defining sub LC parallel resonator including an inductor and a capacitor is inserted between a ground and the connected second ends of the plurality of main LC parallel resonators.
