Claims

[Claim for Utility Model Registration] One side electrode of the series resonator is connected to the input side terminal plate, one side electrode of the parallel resonator is connected to the ground side terminal plate, and the other side electrode of the series resonator is connected to the parallel resonance. In a ladder-type electric filter in which a circuit constituted by connecting the other side electrode of the child and the output side terminal board is housed in a case, the case is made of a conductive metal, and one of the terminal boards 1. A ladder-type electric filter, characterized in that the case also serves as a terminal plate and has a press-contact protuberance protruding inwardly formed on the case, so that the press-contact protuberance is brought into contact with an electrode of a required resonator.
