Title:
PIEZOELECTRIC RESONANT ELEMENT AND PIEZOELECTRIC RESONATOR EMPLOYING IT
Document Type and Number:
WIPO Patent Application WO/2007/026397
Kind Code:
A1
Abstract:
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 the opposite
major surfaces of a rectangular piezoelectric substrate (11). In the nonopposing
regions of both oscillatory electrodes (12, 13), extending portions (12c, 13c)
are provided to extend outward from the center X of the opposing region in the opposite
directions.
