Abstract
A piezoelectric vibrator that generates an elliptical motion using a combination of a longitudinal vibration and a flexural vibration includes a piezoelectric element, three side electrodes, and a power transmission member. The piezoelectric element includes three piezoelectric element layers. The first and second side electrodes electrically connect electrode patterns formed in a diagonal direction among the electrode patterns formed in the first and third piezoelectric element layers of the piezoelectric element, and the third side electrode electrically connects an internal ground electrode of the second piezoelectric element layer to the bottom electrode of the third piezoelectric element layer. The power transmission member is formed in one side of the piezoelectric element to transmit vibration generated from the piezoelectric element to the outside.
