体フイルタ。 A plurality of resonators are arranged on a grounding case, and a coupling board is arranged with a gap between the resonators and the grounding case. Each of the resonators is connected to an electrode, which enters the other main surface of the coupling substrate to form an electrode to which an output terminal is connected, and an insulator disposed between the grounding case and the coupling substrate is formed. In the dielectric filter fixed via a magnetic spacer, a fixing electrode is formed on the surface of the spacer that comes into contact with the grounding case, and the fixing electrode and the grounding case are connected by soldering. dielectric filter.
