Abstract: The stress sensor includes: a magnetic material; a stress applied portion on the magnetic material; a magnet disposed so as to be adjacent to by a magnetic material; a magnetic sensor disposed via the magnetic material so as to be opposed to the stress applied portion, wherein the magnetic sensor detects a magnetic flux emitted from a magnetic domain generated in the magnetic material by a local stress applied to the stress applied portion. The local stress or stress distribution can be detected with a convenience structure, and can obtain a high spatial resolution by using a stress response phenomenon of a single magnetic domain.
