Abstract
A semiconductor acceleration detecting apparatus having a cylinder fixed to a automobile, a piston having a predetermined mass, the piston being inserted in the cylinder and being slidable in an axial direction of the cylinder, a semiconductor pressure sensor disposed so as to face towards a closed space formed by an inner wall of the cylinder and an end wall of the piston, wherein the semiconductor pressure sensor converts pressure in the closed space to an electric potential difference, and an acceleration detecting apparatus including an amplifier and a comparator for detecting acceleration of the automobile in accordance with the electric potential difference outputted from the semiconductor pressure sensor.
