In an acceleration detector that generates an output according to the amount of displacement of a magnetic body, the number of windings of two secondary coils is different, and the difference is calculated when the movable magnetic body is in the detectable region. A detector for acceleration, etc., characterized in that the output voltage due to the difference in the number of windings is determined to be larger than the amount of change in the output voltage across the secondary coil. (2) A movable magnetic body that moves according to acceleration or changes in position, inclination, pressure, etc. is detected by a differential transformer equipped with two primary coils, and the movable magnetic body is connected to the secondary side of this transformer. In an acceleration detector that generates an output according to the amount of displacement of the body, the number of turns of the two primary coils is different, and the difference is calculated when the movable magnetic body is in the detectable region. A detector for acceleration, etc., characterized in that the output voltage due to the difference in the number of windings is determined to be larger than the amount of change in the output voltage across the secondary coil.
