| Abstract | A ladder-type filter includes: one or more series resonators connected in series between an input terminal and an output terminal; two or more parallel resonators connected in parallel between the input terminal and the output terminal; and a path that electrically connects ground terminals of the two or more parallel resonators to each other, electrically connects to ground through only a ground terminal of a parallel resonator located closest to the input terminal or to the output terminal, and includes at least two inductors connected in series in at least two positions of positions between the ground terminals of the two or more parallel resonators and a position between the ground terminal of the parallel resonator located closest to the input terminal or to the output terminal and the ground. |
