Abstract
The invention is related to a magnetic substance detection device for detecting a magnetic substance, including: a magnetoresistive sensor arranged in the middle of a movement path of the magnetic substance; and a lower magnet in which a south pole and a north pole are arrayed along the movement direction of the magnetic substance; and a upper magnet in which a north pole and a south pole are arrayed along the movement direction of the magnetic substance. The lower and upper magnets are arranged with the movement path of the magnetic substance interposed so that the south pole of the lower magnet and the north pole of the upper magnet are opposed to each other, and the north pole of the lower magnet and the south pole of the upper magnet are opposed to each other, whereby the magnetic substance can be detected with high accuracy.
