Claims

[Scope of utility model registration request]

In a piezoelectric vibrator that uses thickness-shear vibration as a vibration mode, a tab is provided on one side of a piezoelectric plate having electrodes and electrode extensions on both sides so as to overlap at least a portion of the electrode extensions on the opposite side. 1. A piezoelectric vibrator characterized in that a support plate is attached along the end portion so as to include the overlapping portion of the tab and the electrode lead-out portion, and the support plate is used as a support portion for attachment to other members.
