Abstract
An acoustic wave element includes a piezoelectric substrate, an IDT electrode, a sidewall, a lid, and an adhesive layer. The IDT electrode is provided on the piezoelectric substrate. The sidewall is provided around the IDT electrode above the piezoelectric substrate. The lid is provided above the sidewall so as to cover a space above the IDT electrode. The adhesive layer is made of an adhesive provided between the lid and the sidewall. The top surface of the sidewall has a groove. The groove is filled with an adhesive, which reduces the protrusion amount of the adhesive.
