Abstract
An acoustic wave device includes a first resonator, a first functional electrode provided on one of first and second main surfaces and a first dielectric film on the one of the first and second main surfaces, a second resonator sharing the piezoelectric layer with the first resonator and including a second functional electrode on one of the first and second main surfaces, a second dielectric film on the first main surface and a third dielectric film on the second main surface. The piezoelectric layer includes first and second resonator portions in which the first and second resonator are respectively provided. When thicknesses of the first resonator portion, the second resonator portion, the first dielectric film, the second dielectric film, and the third dielectric film are represented by tp, tp, ts, ts, and ts, respectively, ts/tp<(ts+ts)/tpis satisfied.
