DEW FORMATION PREVENTION CURTAIN

PROBLEM TO BE SOLVED: To provide a dew formation prevention curtain which does not adversely affect the opening and closing function of a window, less liable to obstruct daylighting property from the window, and is excellent in durability. SOLUTION: The dew formation prevention curtain 1 is provided with: a fabric curtain 2 which is housed wound in a housing case 4 and developed nearly in the state of a plane along a glass window 11 from the housing case 4; and linear conductive heat generating bodies 3a, 3b and 3c attached to the fabric curtain 2 through a wire net 10. The conductive heat generating bodies 3a, 3b and 3c are arranged so that the axial direction (longitudinal direction) of the conductive heat generating bodies 3a, 3b and 3c may cross with the developing direction 6 of the fabric curtain 2 at a right angle. Dew formation on the inner surface of the glass window 11 is prevented by making the conductive heat generating bodies 3a, 3b and 3c generate heat by supplying current controlled by a controller 8.
