ABSTRACT:
The present invention provides a precoated metal sheet for light reflectors having a high diffuse reflectance of visible lights and an excellent heat absorptivity, and also provides the electric or electronic apparatus using it. The precoated metal sheet comprises a metal sheet or plated metal sheet, a visible light reflective coat on one surface of the sheet, and a heat absorptive coat on the other surface of the sheet. The visible light reflective coat has a diffuse reflectance of visible rays of not less than 0.7 in a wavelength of 400 to 700 nanometers. The heat absorptive coat has a total emissivity of infrared rays of not less than 0.7 in the range of wave number of 600 to 3000 cm−1measured at a certain temperature within the range of from 80 to 200 degrees centigrade.
