Abstract
An acoustic wave module includes a hollow space defined by first and second piezoelectric bodies, a support layer, and a first functional element. A second functional element and a shield layer are disposed in the hollow space. The shield layer includes first and second layers disposed on the first functional element side and a second layer disposed on the second functional element side. The second layer adds, to the first layer, a force that causes the first layer to warp so that the first layer at a peripheral end portion and a peripheral end portion approaches the first functional element.
