1. A semiconductor device comprising:

  • a substrate having a first face and a second face opposing said first face, for transmitting light through said first face and said second face;

    a wiring layer provided on said first face of said substrate, having a first region and a second region adjacent to said first region;

    a semiconductor chip having a main face comprising a third region and a fourth region surrounding said third region, which is formed on said first region of said wiring layer for electrically connecting said wiring layer to said fourth region;

    a columnar electrode which takes a columnar form having a third face and a fourth face opposing said third face, said third face being provided on said second region of said wiring layer such that said columnar electrode is electrically connected to said wiring layer;

    a sealant constituted by a single resin, which covers said first face of said substrate such that said fourth face of said columnar electrode and said third region of said semiconductor chip are exposed; and

    an external connection terminal provided on said fourth face of said columnar electrode so as to be electrically connected to said columnar electrode.
