The through-hole overlaps a portion of a wiring line in a plan view. An acoustic wave device further includes an electrode film that is electrically connected to the wiring line in the through-hole, and a protective layer that includes an insulating material and that covers a portion of the electrode film. The protective layer is connected to the cover and the support in the through-hole. Differences in thermal expansion coefficients between the protective layer and the cover and between the protective layer and the support are smaller than a difference in thermal expansion coefficients between the protective layer and the electrode film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acoustic wave device","description":"A through-hole that extends from an upper surface of a cover opposite a support to a lower surface of the support facing a substrate is provided in the support and the cover.
