Abstract
An acceleration sensor element constitutes a piezoresistance type acceleration sensor in which an acceleration sensor chip including a cantilever structure of mass and beam parts and a piezoresistor formed on the beam part is mounted on a main lead which is slanted for positioning the piezoresistor and the center of gravity of the mass part substantially on the same horizontal plane in a mounted state of the sensor. The element thereby improves the reliability and assures such property as other-axis sensitivity of the sensor at the time of shipment.
