Abstract
An exemplary piezoelectric device includes a piezoelectric vibrating piece, on which excitation electrodes are formed, and a piezoelectric frame having a frame portion surrounding the piezoelectric vibrating piece. A plate (e.g., lid or base) is bonded to one surface of the frame portion. Fitting members are provided on both the frame and the plate. When the piezoelectric frame and plate are brought together for assembly, the fitting members fit together (e.g., interdigitate) to provide quick and error-free alignment. Then, the fitting members are bonded together by a bonding material.
