Claim 16:
17. 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 first acoustic wave element includes a first reflector, and the second acoustic wave element includes a second reflector;
the slit is disposed between the first reflector and the second reflector in the direction of acoustic wave propagation; and
the slit includes a plurality of slits that are serially disposed in a direction orthogonal or substantially orthogonal to the direction of acoustic wave propagation.
