Abstract
An acoustic wave deviceincludes a piezoelectric substrateincluding a first surfaceA and a second surfaceB, a support substratebonded to the second surfaceB of the piezoelectric substrate, and a first filterand a second filtera passband of which is higher than that of the first filter, both being on the first surfaceA of the piezoelectric substrate. The first filterand the second filtereach includes an IDT electrode. A thickness of the IDT electrodeof the first filterand a thickness of the IDT electrodeof second filterare different.
