PURPOSE:To obtain a reflecting mirror having superior corrosion resistance, by providing a reflective aluminum layer, a light-transmissive inorganic oxide layer, whose pores are sealed with the carboxylate of ion-group metal, and an insulating layer on a base made of specific metal. CONSTITUTION:On one surface of a base 11 made of a metallic material having a greater ionization potential than that of aluminum, a smoothing layer 12 for smoothing the surface of the base 11 is provided at need. This smoothing layer 12 is formed by applying and hardening or baking an inorganic material paint. The surface of the base 11 or smoothing layer 12 if necessary is coated under vacuum with an aluminum layer 13 constituting a reflective layer. After the surface of the reflective layer 13 is coated under vacuum with a light-transmissive inorganic oxide layer 14, an insulating layer 15 is formed covering the circumferential flanks of the base 11 and layers 12, 13 and 14, and other surfaces of the base 11. Then, the inorganic oxide layer 14 is treated with the carboxylate of ion-group metal, having a low valence, to seal its pores, thereby obtaining a reflecting mirror 10. |
