ABSTRACT:
An acceleration sensor is formed of a housing, an inertia member located inside the housing so as to be freely movable in a longitudinal direction of the housing, a conductor provided on at least an end surface of the inertia member in the longitudinal direction of the housing, a pair of electrodes disposed at one end side of the longitudinal direction of the housing, and electrically connected together by a conductive bridging inertia member. An attractor is disposed at the other end side of the longitudinal direction of the housing and magnetically attracts the inertia member. A stopper is disposed at an opposite side of the inertia member with respect to the electrodes, and abuts against the tip surface of the inertia member when the inertia member moves forwardly. The stopper is disposed at a position which is located off-center with respect to or deviated from the axial center line of the housing.
