A vibrator includes a vibration element having an excitation section which is provided with excitation electrodes, and which excites a thickness shear vibration, and a fixation section electrically coupled to at least one of the excitation electrodes, a vibration attenuator disposed on at least one of principal surfaces of the vibration element, and a support substrate having a coupling electrode which is electrically coupled to the fixation section, and which supports the vibration element, wherein the vibration attenuator is disposed at the fixation section side of the excitation electrodes, and at an outer circumferential edge side of the vibration element from the fixation section in a direction perpendicular to a direction in which the excitation electrodes and the fixation section are arranged side by side. |
