Abstract
A sensor device includes a substrate having a substrate surface, a first IDT electrode positioned on the substrate surface, a second IDT electrode positioned on the substrate surface, a waveguide, and a protective film. The waveguide is positioned on the substrate surface and between the first IDT electrode and the second IDT electrode. The waveguide includes a first immobilized layer positioned on the substrate surface and a second immobilized layer positioned on the first immobilized layer. The second immobilized layer is positioned inside an outer edge of the first immobilized layer as seen in a plan view.
