A stress sensor (60) comprising a magnetic body (10), a stress-acting part (40P) on the magnetic body (10), a magnet (20) disposed adjacent to the magnetic body (10), and a magnetic sensor (30) disposed facing the stress-acting unit (40P) via the magnetic body (10). Magnetic flux discharged from the magnetic domain generated in the magnetic body (10) is detected by the magnetic sensor (30) using local stress applied to the stress-acting part (40P). Local stress or stress distribution can be detected using a simple structure, and high spatial resolution can be obtained using the stress response phenomenon of a single magnetic domain. |
