Abstract
A longitudinally coupled resonator acoustic wave filter includes first and second IDT electrodes on a piezoelectric substrate. A direction in which electrode fingers of the IDT electrodes extend is a first direction, a direction perpendicular or substantially perpendicular to the first direction is a second direction, a ground-side busbar of the first IDT electrode and a hot-side busbar of the second IDT electrode face each other in the second direction, and the longitudinally coupled resonator acoustic wave filter includes a projecting portion, connected to the ground-side busbar of the first IDT electrode, that extends in the second direction toward the second IDT electrode beyond an interdigitated region of the first IDT electrode.
