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