Original Abstract Submitted
An acoustic wave device includes a piezoelectric substrate including a piezoelectric layer, and IDT electrodes on the piezoelectric substrate and including curved IDT electrodes. A direction in which a portion of the electrode finger with a curved shape in the curved IDT electrode is convex is an outer side direction. Acoustic wave resonators include first and second acoustic wave resonators including first and second curved IDT electrodes, respectively. The first and second acoustic wave resonators are connected without another acoustic wave resonator interposed therebetween. When one of the directions in which electrode fingers are arranged is a first direction and a direction opposite to the first direction is a second direction, the outer side direction in the first IDT electrode is the first direction, and the outer side direction of the second IDT electrode is the second direction.
