Abstract
An elastic wave filter device includes first and second reception filters, an input terminal, output terminals, and reference terminals provided on a piezoelectric substrate. The first reception filter includes series resonators and parallel resonators, and the second reception filter includes series resonators and parallel resonators. The reference terminal connected to the parallel resonator connected so as to be closest to the output terminal among the parallel resonators included in the first reception filter, and the reference terminal connected to the parallel resonator connected so as to be closest to the output terminal among the parallel resonators included in the second reception filter, are separated from each other on the piezoelectric substrate.
