PROBLEM TO BE SOLVED: To restrain an increase in coercive force due to an antimagnetic field over a free layer sufficient to write information with low power consumption, irrespective of the thickness of the free layer, moment, etc., whereas magnetoresistive effect elements are miniaturized. SOLUTION: The magnetic memory comprises magnetoresistive effect elements 10 each having a ferromagnetic free layer 16 and a nonmagnetic conductor-made electrode layer 22 on the free layer 16 of the magnetoresistance effect elements 10 so that the magnetic field of a current generated by the electrode layer 22 makes the magnetization of the free layer 16 inverted. The layer 22 has a part laminated on the layer 16. A magnetic material made magnetic layer 23 is provided on a part of the layer 22 which is not laminated on the free layer 16 but on the free layer 16 side of the electrode layer 22, thus increasing the apparent area of the free layer 16.
