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 substratum plate. One of the layers is made so that it has an electric resistance, a pair of electrodes being connected thereto. An electric current is applied in order to generate heat to remove cloudiness or frost on the reflecting surface of the mirror. The mirror may also have a heat wave-reflecting layer for reflecting heat waves from the electric resistance layer.
