In addition, as other experimental data, one side of a transparent electrode film 3 with a diameter of 388 mm x 725 mm was insulated with 50 mm thick urethane foam, and the temperature change was investigated. The results are shown in Table 1 below. Table 2 shows the temperature changes when both sides are insulated with 5cm ring-thick urethane foam! l-1 [Effects of the Invention 1] In short, the present invention consists of laminating a transparent electrode film in which a conductive thin film is deposited on a transparent film base material, and electrically connecting one electrode to the conductive thin film. Since the electrode and the conductive thin film are covered with a transparent protective film, by supplying electricity to the conductive thin film through the electrode, the transparent electrode film can generate heat, for example, radiant heating that emits far infrared rays can be performed. However, since the electrode and transparent electrode film are covered with a transparent protective film, safety can be ensured and transparency can be maintained. For example, even if it is pasted on a window surface, it will not spoil the view from the window, and it will also provide good lighting. This has the advantage that a sufficient amount of energy can be secured, and as a result, radiant heating can be performed on the window surface.
