PURPOSE:To achieve higher productivity by realizing higher acceleration detecting accuracy while facilitating the setting of a reference position as sensor, concerning a magnetic acceleration sensor. CONSTITUTION:This magnetic acceleration sensor has at least a moving body 33 comprising a magnetic material, movable by a mechanical external force freely, in a magnetic field area which is formed with a case 31 near one or a plurality of magnetic detectors 34 mounted on the surrounding wall of the case 31 and a moving space corresponding to the moving body 33. A means is provided to position and hold the moving body 33 at a specified reference position in the magnetic field area or to release the holding. |
