Original Abstract Submitted

an acoustic wave device includes a piezoelectric layer including first and second main surfaces, first and second electrode fingers on the first main surface and respectively connected to an input potential and an output potential, and a third electrode finger on at least one of the first and second main surfaces and connected to a reference potential. the first and second electrode fingers when seen from an electrode finger orthogonal direction orthogonal or substantially orthogonal to a direction in which the first and second electrode fingers extend. a region where the first and second electrode fingers overlap in the electrode finger orthogonal direction is a facing region. the third electrode finger overlaps with at least a portion of at least one facing region when seen from a main surface facing direction in which the first and second main surfaces face each other.
