Abstract
A SAW device includes a piezoelectric substrate, a support substrate which is located on a lower surface of the piezoelectric substrate and has a smaller thermal expansion coefficient than that of the piezoelectric substrate, an IDT electrode located on the piezoelectric substrate, a cover forming a space above the IDT electrode, and a plurality of first strip conductors which extend alongside each other on the cover and at least a part of which overlaps the space when viewed on a plane.
