ABSTRACT:
A surface acoustic wave device includes a piezoelectric substrate and a lid spaced apart from each other oppositely by a specific interval. A comb electrode and a pad electrode are provided to the piezoelectric substrate on a main surface on the lid side, and an external terminal is provided to the lid on a surface on the opposite side to the piezoelectric substrate. Further, the surface acoustic wave device includes a connection electrode that electrically connects the pad electrode and the external terminal, and an insulator interposed between at least one of the main surface of the piezoelectric substrate and the pad electrode and the lid.
