ABSTRACT:
A circuit board for mounting one or more optical devices such as light receiving LSI chips and light emitting LSI chips. The circuit board has a flexible transparent substrate, a window portion which is formed as a slit-like transparent region of the transparent substrate, a plurality of electrodes for bonding the optical devices thereon provided on one surface of the substrate, a plurality of aggregated electrodes provided on the other surface on a region corresponding to the electrodes in a manner extending respectively in the longitudinal direction of the window portion and electrical connection portions penetrating the substrate. Each of the aggregated electrodes is electrically connected with two or more of the electrodes through the electrical connection portion. The circuit board will be used in, for example, an optical reader, an optical printer or the like in such a manner that the light which is coming in and/or going out of the optical device is transmitted through the window portion.
