ABSTRACT:
A color contact image sensor has a light source for emitting illuminating light, a board supporting a sensor element for photoelectrically converting incident light applied thereto, and a light guide fixed to a surface of the board remotely from the light source. The board has a light guide area for transmitting the illuminating light emitted from the light source and applied to the board into the light guide. The sensor element is positioned for receiving light reflected by a subject to which the illuminating light emitted from the light source and passing through the light guide area and the light guide is applied. A color filter is disposed on the board in either a path of the illuminating light emitted from the light source or a path of the light reflected by the subject.
