[Problems to be Solved by the Invention] In the conventional temperature distribution measuring method and temperature detector as described above, regardless of the measuring method, the wire mesh 12 used as the detector has an area of more than a certain extent due to the need for image processing. Is required. For this reason, the metal wires that make up the wire mesh must be made thicker, and the mesh must be made finer. This resulted in the problem that not only did the wire mesh become heavy and difficult to transport and install, but the wire mesh also obstructed airflow, making it impossible to accurately measure temperature distribution.

Therefore, the effective measurement range was approximately 2/3 of the detected area, resulting in a problem of poor efficiency.
