Abstract
On the light-entering surface side of a base material, a coating layerin which a high-refractive layer and a low-refractive layer are sequentially disposed alternately on one on the other is provided for blocking infrared radiation. One of the high-refractive layers is configured by an ITO filmso that the conductivity is increased on the surface of the coating layer. Herein, in view of preventing, to a further extent, the attachment of dirt and dust by providing the conductivity to the surface of the coating layer, it is desirable if the outermost high-refractive layer is made of a transparent conductive material. Moreover, it is desirable if the total layer thickness is 140 nm or smaller for the refractive layers formed outside of the high-refractive layer made of the transparent conductive material.
