ABSTRACT:
The present invention provides a precoated metal sheet, for light reflectors, having a high diffuse reflectance of visible light, 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 undercoat having a thickness of 3 to 30 micrometers provided on at least one surface of the metal sheet or plated metal sheet, and a visible light reflective overcoat having a thickness of 10 to 40 micrometers provided on the visible light reflective undercoat. The visible light reflective undercoat comprises a binder resin and a titanium oxide, a content of the titanium oxide in the visible light reflective undercoat being 40 to 150 parts by weight based on 100 parts by weight of a solid content of the binder resin, and the visible light reflective overcoat comprises a fluororesin-containing binder resin and a titanium oxide, a content of the titanium oxide in the visible light reflective overcoat being 40 to 150 parts by weight based on 100 parts by weight of a solid content of the binder resin.
