Abstract
An acoustic wave device includes a substrate, functional elements on a first main surface of the substrate, an outer support portion on the substrate around a region where the functional elements are disposed, a cover portion opposed to the first main surface of the substrate with the outer support portion interposed therebetween, a support portion in a hollow space defined by the substrate, the outer support portion, and the cover portion, a wiring pattern electrically connected to the functional elements, and a through electrode extending through the substrate and electrically connected to the wiring pattern. A gap is provided between the support portion and the cover portion. A distance from the first main surface of the substrate to an upper surface of the support portion is greater than a distance from the first main surface of the substrate to an upper surface of the functional elements.
