ABSTRACT:
There is provided a piezoelectric resonant element having excellent electrical characteristics in which spurious is suppressed. The piezoelectric resonant element (10) is constituted by sticking a pair of oscillatory electrodes (12, 13), respectively, to both major surfaces of a rectangular piezoelectric substrate (11). In the nonopposing regions of both the oscillatory electrodes (12, 13), extending portions (12c,13c) are provided to extend in the opposite directions outward from the center X of the opposing region.
