Abstract
An acoustic wave device includes a support including a support substrate with a thickness in a first direction, a piezoelectric layer on the support in the first direction, and resonators each including a functional electrode on the piezoelectric layer in the first direction. The support includes first and second space portions at positions where the respective resonators at least partially overlap in plan view in the first direction, the second space portion with an area larger than an area of the first space portion in plan view in the first direction. The piezoelectric layer includes first and second through-holes respectively communicating with the first and second space portions, and the first through-hole has an area larger than an area of the second through-hole in plan view in the first direction.
