Abstract
A surface acoustic wave device includes a SAW having an IDT disposed on a piezoelectric substrate, a conductive pad connected to the IDT, and a bonding substrate, wherein the SAW is bonded to the bonding substrate such that a protective space of the IDT is provided. The bonding substrate includes a through-hole in which an external terminal connection member connected to the conductive pad and an external terminal are disposed. The SAW is bonded to the bonding substrate by an adhesive layer including a solder layer.
