Abstract
A magnetic detection device includes a signal processing circuit that detects a moving position and a moving direction of a magnetic mobile object using an output of a comparing circuit configured to output a signal by comparing an output signal of a magneto-electric transducer element with a threshold. A duration during which an output of the signal processing circuit is in a high level or in a low level is fixed to a period tor a period tdepending on the moving direction of the magnetic mobile object. When switching of the moving direction of the magnetic mobile object takes place within the period tor the period t, the signal processing circuit outputs a position signal same as a position signal indicating a position immediately before the switching of the moving direction of the magnetic mobile object due to hysteresis of the threshold of the comparing circuit.
