Abstract / Hauptanspruch
To obtain a magnetic detection device which can detect a direction of movement of a magnetic moving body immediately right after a reset release of the magnetic detection device. The magnetic detection device includes a signal change detector which detects the peak, bottom, and gradient of an output signal of a first magnetoelectric conversion element group and the peak, bottom, and gradient of an output signal of a second magnetoelectric conversion element group, wherein a direction of movement of a magnetic moving body is detected based on the gradient of increase or decrease of one of the output signal or the output signal at the timing of a detection of the peak or bottom of the other.
