Abstract
An acoustic wave device includes a first acoustic wave resonator including a first piezoelectric film, and at least one second acoustic wave resonator electrically connected to the first acoustic wave resonator. The first acoustic wave resonator includes a first comb-shaped electrode on a first piezoelectric layer and including first electrode fingers connected to an input potential, a second comb-shaped electrode on the first piezoelectric layer and including second electrode fingers interdigitated with the first electrode fingers, and connected to an output potential, and a third electrode connected to a potential different from those connected to the first and second comb-shaped electrodes, and including third electrode fingers, and a connection electrode connecting adjacent third electrode fingers. The second acoustic wave resonator includes fourth and fifth electrode fingers interdigitated with each other. The second acoustic wave resonator is a series arm resonator or a parallel arm resonator.
