ABSTRACT:
A total contact type image sensor includes a transparent substrate, an opaque layer formed on the transparent substrate and having document illuminating windows, a photosensitive layer formed on the transparent substrate and the opaque layer, a plurality of photoelectric conversion elements arranged on the transparent substrate with a predetermined pitch, and a transparent protection layer which covers a surface of a stacked structure which is made up of the transparent substrate, the opaque layer, a photosensitive layer and the photoelectric conversion elements. The photoelectric conversion elements respectively have at least one concave portion in a plan view of the total contact type image sensor. The document illumination windows are respectively formed on a periphery of a corresponding one of the photoelectric conversion elements with a 1:1 relationship, and the document illuminating window respectively have at least one convex portion in the plan view in correspondence with the concave portion of a corresponding one of the photoelectric conversion elements so as to surround the corresponding one of the photoelectric conversion elements.
