ANGULAR VELOCITY DETECTION ELEMENT, ANGULAR VELOCITY DETECTION DEVICE, ELECTRONIC APPARATUS, AND MOVING OBJECT |
| 摘要 |
A gyro element includes a base section, a pair of drive arms connected to the base section, and a detection section adapted to detect an angular velocity applied in a state in which the drive arms are flexurally vibrated in a drive vibration mode, and the drive arms vibrate in phase in the in-plane direction of the base section 21, and vibrate in reverse phase in a thickness direction of the base section 21. |

1. An angular velocity detection element comprising:
a base section; at least two drive arms connected to the base section; and a detection section adapted to detect an angular velocity applied in a state in which the two drive arms are flexurally vibrated in a drive vibration mode, wherein in the drive vibration mode, the two drive arms flexurally vibrate in phase in an in-plane direction of the base section, and flexurally vibrate in reverse phase along a thickness direction that is crossing the in-plane direction. |
