    摘要: A strain sensor element comprises a laminated film which has a magnetic free layer, a spacer layer, and a magnetic reference layer. The free layer has a variable magnetization direction and a out-of-plane magnetization direction. The reference layer has a variable magnetization direction which is pinned more strongly than the magnetization of the free layer. The spacer layer provided between the free layer and the reference layer. A pair of electrodes is provided with a plane of the laminated film. A substrate is provided with either of the pair electrodes and can be strained. The rotation angle of the magnetization of the free layer is different from the rotation angle of the magnetization of the reference layer when the substrate is distorted. Electrical resistance is changed depending on the magnetization angle between the free layer and the reference layer, which allows the element to operate as a strain sensor.
