ABSTRACT:
A full-size image sensor includes a plurality of photoelectric conversion elements formed on a substrate and arranged into a line. A photosensitive surface of each of the photoelectric conversion elements is perpendicular to a document to be scanned. A transparent layer is formed on the substrate so as to cover the photoelectric conversion elements. A light reflecting layer made of a light interrupting member is formed on the transparent layer so as to prevent light emitted from a light source from being directly projected onto the photoelectric conversion elements. The light emitted from the light source is reflected on the document and then projected onto the photoelectric conversion elements directly or after being reflected by the light reflecting layer.
