Abstract

A surface acoustic wave device includes a piezoelectric substrate with an IDT electrode that excites a surface acoustic wave provided on a principal surface, a cover layer opposing the principal surface and that covers the IDT electrode, a support provided in a standing manner around the IDT electrode on the one principal surface, and that, with the cover layer separated from the IDT electrode, supports a piezoelectric-substrate-side surface of the cover layer, and a connector that is provided on the piezoelectric-substrate-side surface of the cover layer and that joins the cover layer and the support to each other. At least a portion of a cover-layer-side end portion of the support exists in the connector. A dimension of the connector in a normal direction to the one principal surface is less than a dimension of the support in the normal direction.
