Abstract:
1. An oscillator comprising: a movable element formed of silicon, the movable element vibrating by electrostatic force; a stationary element supporting the movable element; a temperature detector located in contact with the stationary element, the temperature detector detecting the temperature of the stationary element; a supporting element joined to a joint surface between the movable element and the stationary element, the supporting element supporting the movable element, the stationary element, and the temperature detector on a surface opposite to the joint surface; a surrounding element contacted with the supporting element, the surrounding element and the supporting element surround the movable element; and electrodes provided on a surface of the surrounding element opposite to a surface of surrounding element contacted with the supporting element; a first wiring layer between the movable element and the stationary element; a second wiring layer joined to the temperature detector; and vias passing through the supporting element and the surrounding element and electrically joined to the first wiring layer, the second wiring layer, and the electrodes.
