Abstract

A magneto-resistance element includes a resistance variable layer and a trap layer. The resistance variable layer includes the alloy having B. A resistance of the resistance variable layer changes according to a magnetic field. The trap layer is for trapping the B diffused from the resistance variable layer. With this structure, the B in the resistance variable layer becomes easily trapped in the trap layer and becomes difficult to be diffused to an outside of the magneto-resistance element. A difficulty associated with B diffusion to the outside of the magneto-resistance element can be prevented from occurring.
