DEFORMATION DETECTION SENSOR AND PRODUCTION OF THE SAME

The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced. [0002] The present invention thus provides a deformation detection sensor which comprises: a magnetic resin-containing polymer foam (6) which comprises a magnetic resin (4), in which a magnetic filler is contained, and a polymer foam (5) in which the magnetic resin is included, and a magnetic sensor (3) that detects a magnetic change caused by a deformation of the magnetic resin-containing polymer foam, wherein the magnetic resin has an elastic modulus of 0.1 to 10 MPa, and a production thereof.
