Abstract
An acoustic wave device includes a piezoelectric substrate, a transducer, and a depression. The transducer is disposed on a surface of the piezoelectric substrate, and includes a first bus bar, a first electrode, a second bus bar, and a second electrode. The first bus bar and the second bus bar extend along a second direction. The first electrode has a first end and extends from the first bus bar along a first direction. The first electrode and the second electrode are spaced apart from each other, and a gap is formed between the first end of the first electrode and an edge of the second bus bar. The depression is formed in the piezoelectric substrate and is depressed from the surface of the piezoelectric substrate. The first end of the first electrode is continuously joined to a sidewall of the depression along a depth direction.
