Abstract
An acoustic wave device includes a piezoelectric substrate, interdigital electrodes arranged on the piezoelectric substrate, a first dielectric element arranged between the interdigital electrodes, a second dielectric element that covers the interdigital electrodes and the first dielectric element, and an adjustment element that has been formed on the first dielectric element. The adjustment element has been formed from a material whose specific gravity is greater than that of the first dielectric element and that of the second dielectric element.
