Another is to realize an electrothermal heating function using a transparent conductive thin film formed of indium tin oxide (hereinafter also referred to as "ITO") or the like as a heat generating layer, and to achieve high conductivity, a thick film is required because of the inherent low conductivity of the material of ITO, and the transmittance is reduced due to the color of ITO itself as the thickness of ITO increases, so that the effect of full transparency of the heated product is achieved, but the transmittance is generally lower than 70% or less due to the reduction of the transmittance of the entire product, and thus, some applications in high transmittance scenes cannot be satisfied. In order to overcome the above drawbacks, to achieve the effect that the transmittance is greater than 70% on the premise of achieving the full transparency of the heating product, it is necessary to improve the transmittance of the heating product to which the ITO conductive film is applied.
