Abstract
An acoustic wave device includes a package substrate including a first main surface, and an acoustic wave element chip on the first main surface and including a piezoelectric layer including second and third main surfaces facing each other, and IDT electrodes at the second main surface on a side of the first main surface. The first main surface includes first and second sides facing each other. The second main surface a first edge portion closer to the first side than the second side, and a second edge portion facing the first edge portion. A first inter-outer peripheral edge distance between the first side and the first edge portion is longer than a second inter-outer peripheral edge distance between the second side and the second edge portion. The piezoelectric layer has a Z-axis defining a crystal axis and inclined with respect to a thickness direction of the piezoelectric layer.
