たことを特徴とする梯子型電気濾波器。[Claims for Utility Model Registration] A predetermined unit filter circuit is constructed by accommodating a series resonator and a parallel resonator in a conductive metal case, and the case is electrically connected to the electrodes of the series resonator or parallel resonator. In the ladder-type electric filter, the connecting legs of the terminal plate, which are electrically connected to other electrodes of the series resonator or the parallel resonator, are led out from the opening surface of the metal case. An insulating plate is provided on the inner bottom surface, the lower surface of the metal case is removed to expose the insulating plate, and the connecting legs of the terminal board are bent inward twice to insulate the ends. A ladder-type electric filter is arranged along the bottom surface of a board, and the ends of the connecting leg pieces and the metal case are electrically connected to required conductive paths on a printed circuit board, respectively.
