<P>PROBLEM TO BE SOLVED: To provide a strain detecting element and a pressure sensor capable of highly sensitively performing detection. <P>SOLUTION: This strain detecting element includes: a laminated film that includes a magnetization free layer in which magnetization faces a film surface perpendicular direction when the magnetization direction is changeable and no external strain is applied thereto, a reference layer having the magnetization, and a spacer layer provided between the magnetization free layer and the reference layer; a pair of electrodes perpendicularly energizing the lamination surface of the laminated film; and a substrate provided to at least one of the pair of electrodes. In a state where the substrate is distorted, the rotation angle of the magnetization of the magnetization free layer is different from the rotation angle of the magnetization of the reference layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
