When a portion of the object to be detected 10 reaches 100° C. or higher, the claw-like portion 2 of that portion rises and contacts and conducts with the conductive elongated body 5. Therefore, by measuring this electrical resistance with the electrical resistance measuring means 13, it was possible to discover a local temperature abnormality in the object to be detected 10. Furthermore, since the claw-like portion 2 in the part where the temperature abnormality occurs is in contact with the conductive elongated body 5, the electrical resistance value indicated by the contact and conduction of the claw-like portion 2 is the same as that from the end of the detected object 10. It is proportional to the distance to the temperature abnormality occurring portion 108. Therefore, it was also possible to detect the position of the temperature boundary lightning portion where the temperature reached 100° C. or more.
