Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sensor in which more weight reduction and more flexibility are achieved than with a conventional sensor and sensitivity and accuracy are improved, and a method for manufacturing the sensor.SOLUTION: A sensor comprises: a resin foam 1 including a magnetic filler; and a magnetic sensor 2 for detecting a magnetic change caused by the deformation of the resin foam 1. The resin is a polyurethane resin foam containing a polyisocyanate component, an active hydrogen component, a catalyst, and a foam stabilizer. The resin foam 1 has hardness change differences 0-10 between JIS-C hardness one second after contact with a pressurizing surface of a hardness meter and the JIS-C hardness sixty seconds after that.
