<p>A light-transmitting sheet material including a heat generation layer formed on one of the surfaces of a transmitting sheet material and terminals disposed at suitable positions on the periphery of the heat generation layer to provide a heat generation function, wherein the heat generation layer comprises a selective transmission (reflection) film having a specific wavelength. A protective layer, an insulating layer, etc., are formed on the heat generation layer, as necessary, and are electrically controlled so that it can be suitably adapted to open portions of a building. The sheet material is constituted as a whole into a laminate body, and is provided as heat generation bodies of various variations.</p> |
