Abstract
An acoustic wave device includes a support including a support substrate with a thickness direction in a first direction, a piezoelectric layer on the support, and resonators each including a functional electrode provided to the piezoelectric layer. The support is provided with a hollow portion at a position overlapping at least a portion of each of the resonators in plan view in the first direction. The resonators include a first resonator and a second resonator adjacent to each other. A through hole reaching the hollow portion is provided to the piezoelectric layer between the first resonator and the second resonator.
