ABSTRACT:
A semiconductor acceleration sensor and a method of producing the sensor are characterized in that a pedestal on which a semiconductor acceleration sensor chip including a weight is mounted is integral with a stopper for preventing movement of the weight outside a prescribed range. The semiconductor acceleration sensor is not broken even if an acceleration outside the measurement range is applied. In addition, the semiconductor acceleration sensor exhibits high accuracy and is low in cost.
