Piezoelectric vibrating element

Than conventional to provide a piezoelectric vibration element capable of obtaining a large vibration. The piezoelectric element in the longitudinal direction of the ends of the diaphragm to form a pair of extension portions which are not joined. The support to form a pair of support portions for supporting a pair of extensions of the diaphragm. Support portion to swing extension portion around the contact portion between the pair of contact pieces when and piezoelectric element has a pair of contact pieces in contact with the front and back surfaces of the extension portion is stretchable an extension supported as allowed to.
