Acceleration sensor with direct mounting
First Claim
1. An acceleration sensor comprising:
- an insulating substrate having a pair of signal deriving electrodes formed directly on an upper surface thereof; and
an acceleration detecting element fixed to and electrically connected to said pair of signal deriving electrodes so as to secure said acceleration detecting element, via said electrodes, to said insulating substrate,said acceleration detecting element including first and second piezoelectric elements each having a pair of facing end surfaces and being coupled with each other, said first and second piezoelectric elements being polarized in reverse directions,wherein first end surfaces of each of said first and second piezoelectric elements are electrically connected to said pair of signal deriving electrodes respectively, and opposite end surfaces of each of said first and second piezoelectric elements are electrically connected to each other.

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.
