Abstract

An elastic wave device includes a piezoelectric substrate, an IDT electrode on the piezoelectric substrate, a support member that is provided on the piezoelectric substrate so as to surround the IDT electrode, a cover that covers the support member, via electrodes that penetrate through the support member and the cover, and bumps that are bonded to the via electrodes. The IDT electrode is located in a hollow space that is enclosed by the piezoelectric substrate, the support member and the cover. A protruding portion extends along at least a portion of an outer peripheral edge of a surface of the cover that is on the opposite side from the piezoelectric substrate, and the protruding portion extends in a direction away from the piezoelectric substrate.
