Abstract
A reflecting mirror for use as a rearview mirror in an automobile, the mirror having a plurality of thin layers arranged on a glass plate. One of the layers is made of a transparent dielectric material having a refractive index which is not less than a refractive index of WO.sub.2 and the other is made of a metal material having a reflecting factor ranging between 50-70%. The light introduced into the mirror is reflected at different borders formed in the mirror between the layers so as to provide lights of different phases. Therefore, there is an interference, and, consequently, the mirror provides a certain selected tone in accordance with the value of the optical thickness of the transparent dielectric layer, resulting in an anti-glare effect and a deep color.
