Claim 0:
1. An acoustic wave device comprising:
a piezoelectric substrate;
a first acoustic wave element including at least one first IDT electrode disposed on the piezoelectric substrate; and
a second acoustic wave element including at least one second IDT electrode disposed on the piezoelectric substrate; wherein
an intersecting region of the at least one first IDT electrode and an intersecting region of the at least one second IDT electrode overlap each other in an overlap region in a direction of acoustic wave propagation;
a diffracting component including a slit is provided in the overlap region;
the slit has a dimension in a direction orthogonal or substantially orthogonal to the direction of acoustic wave propagation that is smaller than a wavelength of an acoustic wave excited by the first acoustic wave element and a wavelength of an acoustic wave excited by the second acoustic wave element; and
the wavelength of the acoustic wave excited by the first acoustic wave element is different than the wavelength of the acoustic wave excited by the second acoustic wave element.
