Abstract
A piezoelectric vibrator element is more stably bonded to reduce the displacement with respect to an external force. The piezoelectric vibrator element is provided with a pair of vibrating arm parts extending from a base, and support arm parts extending from the base on both outer sides of the vibrating arm parts in parallel thereto. Further, the piezoelectric vibrator element is bonded on a mounting part in the package with the pair of support arm parts to thereby be fixedly held. Two or more bonding regions of each of the support arm parts are disposed in the longitudinal direction. In the longitudinal direction, the bonding region on the base side is disposed on the base side of the centroid of the piezoelectric vibrator element. Thus, the length from the bonding point to the tip of the vibrating arm part can be shortened, and the displacement at the tip of the vibrating arm part can be reduced with respect to an impact from the outside. On the other hand, in order to suppress the vibration leakage from the vibrating arm part, the bonding region located on the base side is disposed on the centroid side of a connection part between the base and the support arm part.
