Abstract:
A piezoelectric resonator includes a pair of driving electrodes and a pair of lead electrodes that are formed facing each other on the frontside and backside of a piezoelectric plate that operates in a thickness-shear vibration mode. The front and back driving electrodes are formed such that they each have one or more pairs of parallel sides and have the same shape, and their centers face each other. The parallel sides of one of the front and back driving electrodes are formed parallel with either the X-axis or the Z′-axis of the piezoelectric plate, but the parallel sides of the other driving electrodes are formed without being parallel with the X-axis and Z′-axis thereof.
