PROBLEM TO BE SOLVED: To provide a storage element which has superior thermal stability and reduces writing current. SOLUTION: The storage element 3 has a storage layer 17 for keeping information by the magnetization state of a magnetic material; a magnetization fixing layer 31 is provided with respect to the storage layer 17 via an intermediate layer made of an insulator; the orientation of magnetization M1 of the storage layer 17 is changed by impregnating electrons which are spin-polarized in the laminating direction, to have the information recorded in the layer 17; and the specific resistance of a ferromagnetic layer, constituting the storage layer 17, is 8×10<SP>-7</SP>Ωm or higher.
