Abstract
An acoustic wave device includes a piezoelectric film made of lithium niobate or lithium tantalate, first and second busbar electrodes located on the piezoelectric film and opposite to each other, and first and second electrode fingers and each including one end coupled to the first busbar electrode or the second busbar electrode. The acoustic wave device uses bulk waves in a first thickness-shear mode. A first gap is provided between the first busbar electrode and the second electrode finger. A second gap is provided between the second busbar electrode and the first electrode finger. A length of the first gap and the second gap in a direction in which the first and second electrode fingers extend is about 0.92p or longer, where p is a center-to-center distance between the adjacent first and second electrode fingers.
