A contact image sensor miniaturized by using an optical fiber array glass plate as an image focus lens and by forming a photoelectric conversion part and a light emitting part on one surface of the optical fiber array glass plate at the same time, is disclosed. The contact image sense includes: a protective plate having an opening; an optical fiber array glass plate having a plurality of optical fiber arrays disposed vertically through the opening upper and lower surfaces of the optical fiber arrays being polished optically; a photoelectric conversion means which is composed of a photo sense, for converting a incident light into a electrical signal; a detection circuit which converts the electrical signal into a digital signal; a light emitting element which can make a light incident upon a surface of a paper which is placed on a optical fiber of the optical fiber array glass plate; an optical reflection mirror, being placed on the optical fiber array of the optical fiber array glass plate, for reflecting a light emitted from the light emitting element to the surface of the paper.
