Abstract
In an acoustic wave device, a first IDT electrode is provided on a first main surface of a piezoelectric film, and a second IDT electrode is provided on a second main surface of the piezoelectric film. A crystal c-axis of the piezoelectric film is tilted with respect to a direction normal to the first and second main surfaces. A direction of an electric field generated between a busbar of a comb-shaped electrode and end portions of electrode fingers facing the busbar in the first IDT electrode and a direction of an electric field generated between a busbar and end portions of electrode fingers facing the busbar in the second IDT electrode are opposite directions.
