Abstract:
A piezoelectric resonator according to an embodiment of the present invention is a piezoelectric resonator for obtaining a signal of a predetermined resonance frequency from a bulk acoustic wave propagating inside a piezoelectric film. This piezoelectric resonator has a plurality of transducers stacked in a predetermined direction, and a propagation area of the bulk acoustic wave varies in a propagation direction of the bulk acoustic wave.
