Abstract
An acoustic wave element includes a piezoelectric body, an input IDT electrode, an output IDT electrode, a propagation path provided between the input IDT electrode and the output IDT electrode, a first dielectric layer provided on the piezoelectric body so as to cover the input IDT electrode and the output IDT electrode, and a reactive portion provided on the propagation path and configured to react to a substance to be detected or a binding substance configured to bind with the substance to be detected. The main acoustic wave becomes, in the input IDT electrode and the output IDT electrode, a boundary acoustic wave that propagates between the piezoelectric body and the first dielectric layer, and becomes, in the propagation path, a surface acoustic wave that propagates on an upper surface of the propagation path.
