Claims

[Claims for Utility Model Registration] (1) A window portion having a transparent substrate and transparent heat-generating members formed on both surfaces of the transparent substrate and generating heat separately by electric drive; and both surfaces of the transparent substrate. a detection unit that detects physical quantities related to the cloudy state of the vehicle and outputs the detected physical quantities as electrical detection signals; and a control unit that selects and drives a transparent heat generating member to be driven in accordance with the detection signal. Features anti-fog window components. (2) The cloudy state is caused by dew condensation, frost formation, or
The anti-fog window member according to claim 1, wherein the detection unit includes a fog sensor due to icing. (3) The anti-fog window member according to claim 1, wherein the window portion is a rear window for an automobile. (4) The anti-fog window member according to claim 1, wherein the window portion is a moonroof for an automobile. (5) The anti-fog window member according to claim 3 or 4, wherein the physical quantities related to the fogging state are temperature and humidity inside and outside the vehicle interior. (6) The transparent heat generating member is divided into a plurality of areas on the same surface of the window portion, and consists of a plurality of unit transparent heat generating members each generating heat separately, and the detecting section is configured to detect each of the plurality of unit transparent heat generating members. The anti-fog window member according to claim 1, wherein the control unit selects a unit transparent heat generating member to be driven. (7) The anti-fog window member according to claim 1, wherein the physical quantity related to the fogging state is the degree of scattering on the window surface of light reflected on the window surface.
