とする梯子型電気濾波器。[Claims for Utility Model Registration] A series resonator and a parallel resonator are housed in a case, and a connecting protrusion protrudes from the side of the case to electrically connect with the series resonator or parallel resonator. In a ladder-type electric filter constituting a basic unit circuit of a filtering circuit, the case is made of a conductive metal with openings on both sides, and the basic unit circuit can be formed by connecting the metal case with a series resonator or a parallel resonator. A plurality of terminal plates that serve as conductive paths, have connecting protrusions connected to one edge of the metal case, and are electrically connected to the series resonator or the parallel resonator from the opening surface on the other side of the metal case. A ladder-type electric filter characterized by a protruding connecting protrusion formed on the top.
