Abstract
An acoustic wave device includes: an acoustic wave chip including an acoustic wave element formed therein; a multilayered substrate including the acoustic wave chip mounted on an upper surface thereof; a first ground terminal formed on a lower surface of the multilayered substrate and electrically coupled to a ground electrode of the acoustic wave chip; a second ground terminal formed on the lower surface; a signal terminal formed on the lower surface and electrically coupled to a signal electrode of the acoustic wave chip; and a shield layer formed at least on the upper surface, on the lower surface, or between the lower surface and the upper surface of the multilayered substrate so as to overlap with at least a part of the acoustic wave chip, not electrically coupled to the first ground terminal in the multilayered substrate, and electrically coupled to the second ground terminal.
