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 on the support, and resonators each including a functional electrode on the piezoelectric layer in the first direction on the piezoelectric layer. The support includes space portions therein at positions where the functional electrodes at least partially overlap in a planar view in the first direction. The support includes a lead portion communicating with at least one of the space portions in a planar view in the first direction, at a position that does not overlap the space portion. At least one lead portion communicates with at least two of the space portions. The piezoelectric layer includes a through-hole penetrating the piezoelectric layer at a position overlapping the lead portion in a planar view in the first direction.
