Abstract
An acoustic wave device includes a support substrate, a piezoelectric layer, and an IDT electrode. The piezoelectric layer is directly or indirectly provided on the support substrate. The IDT electrode includes a plurality of electrode fingers and is provided on a main surface of the piezoelectric layer. The thickness of the piezoelectric layer is about 1λ or less when a wavelength of an acoustic wave determined by an electrode finger period of the IDT electrode is defined as λ. The support substrate is an A-plane sapphire substrate.
