Claim:
1. A memory element, comprising: a memory portion that has a magnetization perpendicular to a film face, wherein the magnetization is configured to change; a magnetization-fixed portion that has a magnetization that is perpendicular to the film face and is a reference for the information stored in the memory portion; an insulating portion that is provided over the magnetization-fixed portion and the insulating portion is between the memory portion and the magnetization-fixed portion; and an underlying layer, the magnetization-fixed portion is over the underlying layer, wherein the insulating portion includes a first oxide film, and the memory portion includes a first face and a second face opposite the first face, and the first face comes into contact with first oxide film, and the second face comes into contact with a second oxide film, and wherein a magnitude of an effective diamagnetic field which the memory portion receives is smaller than a saturated magnetization amount of the memory portion.
