An anti-condensation device having an electric heating element and method whereby said heating element is woven horizontally on an insulation plate and is sufficiently enlarged at the central portion to cause the temperature to be the same at every portion of the mirror face of the mirror in which it is used, and because of the heat produced by the heating element and conducted to the face of the mirror, when this mirror is installed in a bathroom or place where there is much steam and vapor, there is a method to cause the temperature of the reflective surface of said mirror to be 7 DEG -10 DEG C (18 DEG F) higher than that of temperature of the room or the adjacent atmosphere, so that it is possible to prevent water vapor dispersed in the air from condensing on the reflective surface of the mirror.
