Claims

[Claims for Utility Model Registration] A series resonator and a parallel resonator are housed in a synthetic resin case to constitute a predetermined basic unit circuit, and the electrodes of the series resonator or parallel resonator can be connected from both sides of the case. In a ladder-type electric filter in which the connecting leg pieces of the terminal board to be electrically connected are guided to the outside, on the bottom surface of the synthetic resin case, at the lower position of each connecting leg piece, A mounting groove having a width and a depth approximately equal to the thickness of the connecting leg is formed, and each connecting leg piece of the terminal board is bent inward twice and the end thereof is fitted into the mounting groove. A ladder-type electric filter characterized in that the ends of the connecting legs are electrically connected to required conductive paths on a printed circuit board.
