像読取装置。[Claims for Utility Model Registration] An EL light emitting element having at least an opaque conductive film and a light receiving element are arranged with an insulating layer interposed therebetween, and the light emitted from the EL light emitting element is arranged on the opposite side of the light receiving element. In an image reading device in which the opaque conductive film is provided with a light entrance window for reflecting light from the document surface and guiding the reflected light to the light receiving element, the document surface side surface of the opaque conductive film is made of an opaque film having a high specular reflectance. An image reading device characterized by using a conductive film.
