ABSTRACT:
An acceleration sensor is formed of a magnet having a magnetizing pattern in which N and S poles are alternately arrayed in one direction, a housing for slidingly holding the magnet in one direction, and a magneto-electric converting element provided within the housing facing the magnet. The acceleration sensor detects a change in speed applied to the acceleration sensor from the output of the magneto-electric converting element.
