    Abstract: A silicon oxide film 113 is formed on the vibrating parts 102 and 103 of an MEMS-type electrostatically-actuated flexural vibrator. At least one structure where no oxide film is formed is provided near the vibrating parts 102 and 103. By employing a structure in which both ends of the structure and both ends of the vibrating parts 102 and 103 are integrally formed, a compressive stress is applied to the vibrating parts 102 and 103. As a result, the frequency temperature characteristics can be improved.

    Abstract: An electrostatic vibrator has a vibrating plate including beam-shaped vibrating parts each fixed at opposite ends thereof and configured for electrostatic actuation to perform flexural vibration, and temperature compensation parts connected to the vibrating parts. A silicon oxide film covers each of the vibrating parts but not the temperature compensation parts. A substrate is mounted in parallel relation to the vibrating plate. An oxide layer is disposed between the substrate to the vibrating plate. Electrodes are formed on the substrate and arranged on opposite sides of each of the vibrating parts.
