ABSTRACT:
A piezoelectric vibrating reed includes a piezoelectric plate made of a piezoelectric material, a pair of exciter electrodes formed on outer surfaces of the piezoelectric plate and configured to vibrate the piezoelectric plate when a predetermined voltage is applied thereon, and a pair of mount electrodes electrically connected to the pair of exciter electrodes, respectively. One mount electrode in the pair of mount electrodes is formed on one surface (under surface) of the piezoelectric plate and the other mount electrode is formed on the other surface (top surface) of the piezoelectric plate in a state not to oppose the one mount electrode with the piezoelectric plate in between. Accordingly, not only can power be saved, but also higher performance can be achieved by lowering the R1 characteristic and thereby enhancing the vibration characteristic.
