Original Abstract Submitted
An acoustic wave device includes a piezoelectric substrate including an acoustic reflection layer and a piezoelectric layer on the acoustic reflection layer, and an IDT electrode on the piezoelectric substrate and including electrode fingers. When a wavelength defined by an electrode finger pitch of the IDT electrode is λ, a thickness of the piezoelectric layer is about 3λ or smaller. The electrode fingers include at least one electrode layer. A sum total of a thickness of the at least one electrode layer converted based on a density ratio of the at least one electrode layer and Al assuming that the at least one electrode layer includes Al is a same or larger than the thickness of the piezoelectric layer.
