ミツクフイルた。 A filtering circuit element comprising a piezoelectric resonator and a terminal plate that contacts and conducts with the electrode surface of the resonator is housed in an insulating case, and a long and thin terminal leg for connecting to an external circuit is protruded from the terminal leg. The opening of the insulating case is sealed with a resin-based insulating sealant and a sealing plate made of an insulating thin film inside the insulating case and supporting the sealing agent, the sealing plate The ceramic film is characterized in that the ceramic film has a convex shape that comes into contact with the upper end surface of the filter circuit element and extends in the direction in which the filter elements are aligned.
