Abstract

An acoustic wave device includes a support with a thickness in a first direction, a piezoelectric layer extending in the first direction, and a functional electrode on a main surface of the piezoelectric layer and including first electrode fingers extending in a second direction intersecting with the first direction, a first busbar electrode connected to the first electrode fingers, second electrode fingers facing any of the first electrode fingers in a third direction perpendicular or substantially perpendicular the second direction and extending in the second direction, and a second busbar electrode connected to the second electrode fingers. The piezoelectric layer includes a first piezoelectric body in contact with the functional electrode and a second piezoelectric body with a different dielectric polarization than that of the first piezoelectric body, and a thickness of the first piezoelectric body is less than or equal to a thickness of the second piezoelectric body.
