Abstract
An acoustic wave device includes a support substrate, a piezoelectric layer overlapping the support substrate viewed in a first direction, a functional electrode on at least a first main surface of the piezoelectric layer, and a wiring electrode connected to the functional electrode. A space is provided on a second main surface side opposite to the first main surface of the piezoelectric layer. The space is covered with the piezoelectric layer, the wiring electrode covers a portion of the functional electrode, and an air gap or an insulating film is provided between the functional electrode and the wiring electrode in a region where the functional electrode is covered with the wiring electrode.
