Abstract
As acceleration sensor has an insulating substrate, a pair of signal deriving electrodes provided on one surface and an acceleration detecting element electrically connected to the pair of electrodes. The acceleration detecting element is provided with first and second piezoelectric elements, having a pair of facing end surfaces, which are directly or indirectly coupled to each other to be polarized in reverse directions. First end surfaces of the first and second piezoelectric elements are electrically connected to the pair of signal deriving electrodes respectively while other end surfaces, being opposite to the first end surfaces, of the first and second piezoelectric elements are electrically connected with each other.
