Abstract
A capacitive acceleration detector in which a fixed electrode is provided on a supporting substrate of a pedestal except opposite a diaphragm of an acceleration detecting beam. A broken or missing acceleration detecting beam is reliably detected because the electrical capacitance between a movable electrode and the fixed electrode is almost zero when the acceleration detecting beam breaks off at the diaphragm.
