Abstract

See full text

An acoustic wave device of the present invention has a piezoelectric substrate, an excitation electrode arranged on the piezoelectric substrate, an electrode pad arranged on the piezoelectric substrate and electrically connected to the excitation electrode, and a cover arranged on the piezoelectric substrate so that a oscillation space is arranged between the cover and the excitation electrode. The cover has inside it a via conductor electrically connected to the electrode pad and is curved so that its surface facing the piezoelectric substrate approaches the excitation electrode side with respect to an upper surface of the piezoelectric substrate from a position of contact with the via conductor.
