Abstract
An acoustic wave device includes a substrate, first and second resonators above the substrate, and an energy confinement portion. The first resonator includes a first piezoelectric film including a first main surface facing a second main surface, both having anisotropy. First and second electrodes are provided on the first or second main surface. The second resonator includes a second piezoelectric film including a third main surface facing a fourth main surface, both having anisotropy. Third and fourth electrodes are provided on the third or fourth main surface. In the first resonator, a first excitation portion is where the first and second electrodes overlap or where the first electrode faces the second electrode. In the second resonator, a second excitation portion is where the third and fourth electrodes overlap or where the third electrode faces the fourth electrode. The first and second excitation portions have shapes including length directions that differ.
