子。[Claims for Utility Model Registration] (1) Two piezoelectric elements and two electrode plates for applying an electric field to each of the two piezoelectric elements are provided, and the electrode plates are attached to both ends of the flexible substrate. An electrode part is provided that contacts the piezoelectric element, and a lead-out electrode part is provided in the middle part to connect the electrode part, and one of the electrode plates is arranged in the center so that the electrode parts at both ends face outward. The other electrode plate is bent at the center so that the electrode parts at both ends are in contact with the inner surfaces of the two piezoelectric elements. 1. A piezoelectric vibrator, characterized in that the piezoelectric vibrator is bent at a portion thereof, and electrode portions at both ends thereof are disposed so as to be in contact with the outer surfaces of the two piezoelectric elements. (2) In paragraph 1 of the claims for utility model registration,
The two electrode plates have the same shape, and the flexible substrate has a notch in which the lead electrode appears when the electrode parts at both ends are bent at the center so as to face inward. Piezoelectric vibrator.
