ABSTRACT:
A piezoelectric vibrator including a pair of first piezoelectric elements having the same rectangular parallelepiped shape and polarized in opposite directions; and a pair of second piezoelectric elements, having the same rectangular parallelepiped shape and respectively attached to a face of the first piezoelectric element, and polarized in the same direction. In the piezoelectric vibrator the first piezoelectric elements are longer than the second piezoelectric elements, and the first piezoelectric elements vibrate in a longitudinal direction and the second piezoelectric elements vibrate in a bending direction when electrical signals are inputted.
