Abstract
A composite substrate includes in this order: a piezoelectric layer; a reflective layer including a low-impedance layer containing silicon oxide and a high-impedance layer; and a support substrate. The low-impedance layer has a density of 2.4 g/cmor less. The high-impedance layer has formed therein an amorphous region.
