Abstract
An inertia force sensor with a damper. The damper includes a cantilever for a movable part disposed in a movable electrode protruding therefrom, and a cantilever for a fixed part disposed in a support portion for the movable part or a support portion for the fixed part and protruding therefrom. The damper allows the cantilever for the movable part and the cantilever for the fixed part to contact each other before the movable electrode contacts the support portion for the movable part and the support portion for the fixed part. As a result, it is possible to prevent a stopper from being damaged and to improve the reliability of the sensor.
