PROBLEM TO BE SOLVED: To provide a heat glass arranged by making an appropriate combination of an exothermic unit with a transmittance of 80% or more in a wavelength region of 400-1500 nm, and a material of 1% or less in both transmittance and reflectance, and forming the exothermic unit on a front face and/or a backside of a glass board with good adhesion, which is superior in water resistance and pressure resistance and adaptive to a larger size of a glass board (100×100 cm or larger in size).SOLUTION: A heat glass system comprises: an exothermic unit composed of a thin film formed by preparing a paste of materials, i.e. ITO(indium-tin-oxide) prepared by thermal decomposition and NTA glass (conductive glass including, as primary components, oxides of vanadium, barium and iron) and making a print of the paste on a glass board by screen printing, followed by sintering; electrodes for power source supply composed of a silver thin film formed in the same way; and a silicone film which makes a cover for ensuring a water resistance and the performance of being resistant against (electric) pressure. Forming holes extending through the glass board from its front face to the backside, a non-heating area in a wiring region can be reduced and a compact system including a set of heat glass boards can arranged.SELECTED DRAWING: Figure 1 |
