Abstract
An acoustic wave device includes a first acoustic wave filter including a first piezoelectric substrate and first resonators on the first piezoelectric substrate, and a second acoustic wave filter including a second piezoelectric substrate and second resonators on the second piezoelectric substrate. The first and second resonators are opposed to each other with a gap therebetween. The first and second resonators each include a heat-generation resonator in which a heat generation range has a highest temperature at a time of signal application. The heat generation ranges of the heat-generation resonators do not overlap each other in plan view.
