Original Abstract Submitted

An acoustic wave device includes first and second piezoelectric layers and an IDT electrode. The second piezoelectric layer is located above the first piezoelectric layer in a first direction. The IDT electrode includes first and second busbar electrodes and first and second electrode fingers. The first and second busbar electrodes oppose each other. The first electrode finger is provided to the first busbar electrode and extends toward the second busbar electrode. The second electrode finger is provided to the second busbar electrode and extends toward the first busbar electrode. The first and second electrode fingers are sandwiched between the first and second piezoelectric layers in the first direction. The first and second electrode fingers extend in a second direction which intersects with the first direction and are located to overlap each other as seen in a third direction perpendicular or substantially perpendicular to the second direction.
