Abstract
An object is to provide a resonator and a vibrator with a high Q value in which dissipation of vibration energy in vibration of the vibrator is small, and a thickness of a support part of the vibrator of a beam structure is made thicker than a thickness of the vibrator and the support part is formed in axisymmetry with respect to a length direction of a beam. By this configuration, brittleness of the support part is improved and loss of vibration energy from the support part is reduced and also loss of vibration energy resulting from surface roughness of a surface of the vibrator can be reduced, so that a resonator having a high Q value can be provided.
