Title: Acceleration sensor

Abstract: An acceleration sensor is disclosed which includes a capacitance-typeacceleration detection element mounted on a ceramic base plate. Theelement comprises a movable electrode mounted between a pair of fixedelectrodes. Acceleration of the sensor in a measurement direction causesthe movable electrode to move relative to the fixed electrodes and theelement has opposite ends in a direction perpendicular to the measurementdirection. The acceleration detection element is mounted on the base at afirst one of the opposite ends. Accordingly, the mounting surface of theacceleration sensor is parallel to the direction of acceleration to bedetected. Thus the acceleration sensor can be surface-mounted on a printedboard, and more be easily mounted in an automobile air bag control systemor the like.
