摘要

A photosensor includes a substrate; a photoconductive layer formed on the substrate; a pair of electrodes mounted on and electrically connected to the photoconductive layer; a light reception portion formed between the electrodes; and a protective layer formed on the light reception portion; wherein an organic silicon film with a small content of metal ion is formed at least at the uppermost portion of the protective layer.
