Original Abstract Submitted
An acoustic wave device includes a piezoelectric body layer having a crystal axis and an IDT electrode on the piezoelectric body layer. When an acoustic wave propagation direction is a first direction and an orthogonal or substantially orthogonal direction is a second direction, the crystal axis of the piezoelectric body layer is inclined in the second direction with respect to a thickness direction. The IDT electrode includes first and second busbars that oppose each other, and first and second electrode fingers and each including one end connected to any one of the first and second busbars. A region where the adjacent electrode fingers overlap each other in the first direction is a cross region which includes a central region positioned on a center side in the second direction, and first and second edge regions that oppose each other with the central region interposed therebetween in the second direction.
