Therefore, as described above, the mirror can be sufficiently used with only the power source of the car's battery, and the mirror can be heated effectively. Furthermore, by protecting the back surface of the planar heating element 16, heat retention can be improved due to the heat insulation effect, and thermal efficiency can be increased. Note that since the purpose of heating the mirror 12 is to prevent frost formation and fogging of the mirror, it is not actually necessary to heat the planar heating element 16 to such a high temperature, and it is possible to use only a small amount of electric power. Also, electrically, the power supply between the planar heating element 16 and the battery inside the vehicle is turned on and off.
Any settings can be made, such as providing a switch to turn the heating element 16 on and off to energize the sheet heating element 16 when necessary, or switching between high and low temperatures.
