Abstract
An acoustic wave device includes a piezoelectric layer and a pair of electrodes. In a cross-section including first and second directions, at least one electrode of the pair of electrodes includes top, bottom, first side, and second side surfaces, the bottom surface being opposed to the top surface and closer to the piezoelectric layer than the top surface. A first angle between the first side surface and the first main surface is different from a second angle between the second side surface and the first main surface, and at least one of the first angle and the second angle is about 80° or larger.
