Abstract
A highly reliable surface acoustic wave device includes wiring lines that do not easily rupture at a three-dimensional wiring portion. The surface acoustic wave device includes a plurality of surface acoustic wave elements located on a piezoelectric substrate, a supporting member arranged on the piezoelectric substrate so as to enclose vibrating portions including electrodes such as IDT electrodes, and a cover member stacked so as to cover openings of the supporting member and to define hollow spaces facing vibrating electrodes. Furthermore, a three-dimensional wiring portion at which a first wiring line and a second wiring line are stacked with an insulating layer interposed therebetween is provided on the piezoelectric substrate. The three-dimensional wiring portion is enclosed by the supporting member, and thereby disposed inside a space enclosed by the piezoelectric substrate, the supporting member, and the cover member.
