Abstract

A surface acoustic wave device includes, a first substrate, a surface acoustic wave chip attached to the first substrate, and a second substrate that hermetically seals the surface acoustic wave chip. At least one of the first and second substrates includes. The first and second substrates have respective joining surfaces. An electric circuit is formed on a surface area of the first substrate other than the joining surfaces.
