Angle sensor device

An angle detecting device which measures angle position information and/or angular velocity information on a movable object is provided with a measurement part of one or more magnetic encoding fields arranged at a movable object, one or more magnetic field detectors, and angle position information and/or angular velocity information. When the one or more magnetic encoding fields where it moves with a movable object pass along a circumference region of a magnetic field detector, the one or more magnetic field detectors are constituted so that a signal generated by the magnetic encoding field may be detected. And based on a detection signal, a measurement part of the angle position information and/or angular velocity information is constituted so that angle position information and/or angular velocity information on a movable object may be measured.
