Abstract
An acoustic wave device includes a substrate, a functional element provided on the substrate, a cover layer provided on or above the substrate to cover the functional element, and a protection layer that covers the cover layer. The cover layer includes a curved portion that is curved to protrude outward. A hollow space is defined between the curved portion and the substrate, and the functional element is provided in the hollow space. The acoustic wave device also includes a conductive portion that is provided between the curved portion and the protection layer and extends along a surface of the curved portion.
