1. An optical circuit board for adapted mounting one or more LSI chips for emitting and/or receiving light, comprising:

  • a transparent substrate;

    a window portion which is formed as a slit-like transparent region of said transparent substrate for transmitting light coming in and going out of said LSI chip;

    a plurality of electrodes provided on a first primary surface of said transparent substrate corresponding to said LSI chip respectively and disposed at least on one side of said window portion along the longitudinal direction of said window portion;

    a plurality of aggregated electrodes provided on a second primary surface on a region corresponding to said electrodes in a manner extending respectively in the longitudinal direction of said window portion, said second primary surface being opposite to said first primary surface with reference to said transparent substrate; and

    an electrical connection portion penetrating said transparent substrate;

    whereineach of said aggregated electrodes is electrically connected with a plurality of electrodes which constitute a part of said electrodes through said electrical connection portion, respectively.
