Abstract
A filter device includes acoustic wave resonators each including a piezoelectric substrate including a piezoelectric layer with first and second major surfaces, a first IDT electrode on the first major surface, and a second IDT electrode on the second major surface, and through electrodes penetrating the piezoelectric layer. Continuous circuits including acoustic wave resonators each including the first and second IDT electrodes are continuously connected. Each of the first and second IDT electrodes of the acoustic wave resonators includes a pair of busbars. The continuous circuits include wires each including the busbars. The wires located at ends of the continuous circuits are each an end portion wire including the busbars of the first and second IDT electrodes in each of the acoustic wave resonators provided with the busbars included in the end portion wires are connected by the through electrode.
