A storage element includes a storage layer which has magnetization perpendicular to its film surface and which retains information by a magnetization state of a magnetic substance, a magnetization pinned layer having magnetization perpendicular to its film surface which is used as the basis of the information stored in the storage layer, an interlayer of a non-magnetic substance provided between the storage layer and the magnetization pinned layer, and a cap layer which is provided adjacent to the storage layer at a side opposite to the interlayer and which includes at least two oxide layers. The storage element is configured to store information by reversing the magnetization of the storage layer using spin torque magnetization reversal generated by a current passing in a laminate direction of a layer structure including the storage layer, the interlayer, and the magnetization pinned layer. |
