Abstract
In an acoustic wave device including a piezoelectric material substrate and supporting body bonded with each other through a bonding layer, it is an object to provide the acoustic wave device having the structure for further improving the propagation loss and temperature characteristics of frequency of an acoustic wave. An acoustic wave device includes a piezoelectric material substrate, an electrode on the piezoelectric material substrate, a supporting body, and a bonding layer for bonding the piezoelectric material substrate and the supporting body. The bonding layer is composed of quartz crystal.
