Abstract
An acoustic wave device includes first and second acoustic wave resonators, each including a piezoelectric layer and a functional electrode, and an acoustic coupling layer laminated between the piezoelectric layer of each of the first and second acoustic wave resonators. Each of the functional electrodes of the first and second acoustic wave resonators includes at least one pair of electrode fingers. In each of the first and second acoustic wave resonators, when a thickness of the piezoelectric layer is defined as d and a center-to-center distance of the electrode fingers adjacent to each other is defined as p, d/p is about 0.5 or smaller. The first and second acoustic wave resonators face each other across the acoustic coupling layer.
