Abstract

PURPOSE:To obtain a color mirror having superior durability by forming a highly reflective metallic layer and an anodic oxide layer on the surface of a glass plate. CONSTITUTION:A tantalum layer 2 as a metallic layer and a tantalum pentoxide layer 3 ad an anodic oxide layer are formed on the smooth surface of a glass plate 1 to obtain a color mirror undergoing little change with the lapse of time and having superior durability. When DC voltage is changed during anodic oxidation to change the thickness of the film 3, the color of the resulting color mirror can be varied by the change of interference colors.
