<p>Disclosed herein is an acceleration sensor which comprises an insulating substrate (6), a pair of signal deriving electrodes (8,9) provided on its one major surface and an acceleration detecting element (2,3,4) electrically connected to the pair of electrodes (8,9). The acceleration detecting element (2,3,4) is provided with first and second piezoelectric elements (2,3), having a pair of facing end surfaces, which are directly or indirectly coupled to each other to be polarized in reverse directions. One end surfaces of the first and second piezoelectric elements are electrically connected to the pair of signal deriving electrodes (8,9) respectively while other end surfaces, being opposite to the first end surfaces, of the first and second piezoelectric elements (2,3) are electrically connected with each other. <IMAGE></p> |
