Abstract
A piezoelectric device includes a piezoelectric substrate, a conductive pattern which is provided on one main surface of the piezoelectric substrate and which includes an IDT electrode, a supporting layer which is arranged on the one main surface of the piezoelectric substrate so as to surround the periphery of an IDT-forming region in which the IDT electrode is provided and which has a thickness greater than that of the IDT electrode, and a cover layer which is arranged on the supporting layer and which covers the IDT-forming region. The supporting layer includes removed sections provided at a plurality of positions at least in a region close to the IDT-forming region, the removed sections being obtained by partially removing a portion of the supporting layer to be bonded to the one main surface of the piezoelectric substrate.
