To freely move an object provided with a magnetic substance in the x, y-directions and simplify its support mechanism.

This magnetic substance moving device is provided with a pair of carriers 2, 3, a magnetic substance train 4 linearly arranged with a magnetic substance on one carrier, and a moved magnetic substance 1a arranged on one side face of the other carrier. Both or one of the magnetic substance train 4 and the moved magnetic substance 1a is a magnet, the magnet forms the magnetic flux perpendicular to the moving plane of the carrier, and they are magnetized so that all magnetic flux is faced in the same direction. Drive mechanisms are provided on a pair of carriers, and the carriers are moved by the drive mechanisms so that the moving direction of the magnetic substance train provided on one carrier and the moving direction of the other carrier cross each other.
