Abstract
A surface acoustic wave device includes a piezoelectric substrate, a dielectric film, IDT electrodes, and a resin member. The surface acoustic wave device includes a resin contact region where the piezoelectric substrate and the resin member are in direct contact with each other. The resin contact region has a shape surrounding the IDT electrodes. Because the resin member exhibits a strong adhesion force with respect to the piezoelectric substrate, peeling-off between the piezoelectric substrate and the resin member is significantly reduced or prevented, and an airtight condition is maintained in the interior of the surface acoustic wave device.
