Abstract
An acoustic wave device includes an acoustic wave element substrate, filter electrodes on a first surface of the acoustic wave element substrate, a first insulator layer covering a second surface of the acoustic wave element substrate, and a second insulator layer laminated on the first insulator layer and sandwiching the first insulator layer between the second insulator layer and the acoustic wave element substrate. The products of propagation speeds of an acoustic wave in those layers and densities of those layers satisfy a predetermined relationship.
