PROBLEM TO BE SOLVED: To provide a mirror formed out of a material having a small thermal conductivity coefficient as well as a large thermal expansion coefficient like plastic, and further formed to have stability in a heated state. SOLUTION: This mirror is characteristic in that the structure consists of a substrate having a front surface and a rear surface, a reflecting layer of high reflectance but low emittance to cover the front surface of the substrate for forming the mirror surface thereof, and a low emittance reflecting layer to cover the rear surface of the substrate. Also, the mirror is characteristic in that the row emittance reflecting layer of the rear surface is capable of reducing a thermal energy quantity absorbed via the rear surface of the substrate for the reduction or prevention of uneven heat applied thereto. |
