ABSTRACT:
An acoustic wave device includes a substrate, a device chip that has a piezoelectric substrate and is flip-chip mounted on a surface of the substrate, a first insulation layer that has a dielectric constant lower than that of the piezoelectric substrate and is provided on a surface of the device chip opposite to another surface that faces the substrate, and a metal seal part that seals the device chip.
