Abstract
There is provided an acceleration sensor that is capable of detecting acceleration with high precision and capable of reducing the size and cost due to its simple structure. The acceleration sensor comprises: a pair of cantilevers arranged on a same straight line or almost in parallel in such a manner that positions of fixed ends and free ends are arranged to face in opposite directions from each other, and each of the free ends has a degree of freedom to deflect along a same direction; a pair of magnetic field generating devices mounted respectively to each of the free ends for generating magnetic fields; and a pair of magnetic field detecting devices arranged to face each of the magnetic field generating devices, respectively, for detecting directions of the magnetic fields generated by each of the magnetic field generating devices.
