Abstract
An inertial sensor such as an acceleration sensor or gyro can have superior impact resistance by regulating displacement of a weight portion in the direction of an upper limit. The sensor includes a sensor portion that has a fixing part, a weight portion the height of which is a predetermined size shorter than that of the fixing part, and a beam portion that links the weight portion and the fixing part; a plate-like first stopper portion that covers the weight portion and is bonded to the fixing part with clearance of a predetermined size from the weight portion; and a flat, plate-like second stopper portion that is connected to the fixing part via a bump of a predetermined height on the side opposite the first stopper portion.
