1. An optical device comprising:

  • a substrate having an obverse surface and a reverse surface facing away from each other;

    an obverse-surface conductive layer formed on the obverse surface of the substrate, the obverse-surface conductive layer including a first obverse-surface conducting region and a second obverse-surface conductive region;

    a reverse-surface conductive layer formed on the reverse surface of the substrate;

    a first conductive part extending through the substrate and overlapping with the first obverse-surface conducting region and the reverse-surface conductive layer as viewed in a thickness direction of the substrate;

    an optical element disposed on the obverse-surface conductive layer; and

    a reflector disposed on the substrate, the reflector having an inner surface that surrounds the optical element as viewed in the thickness direction,wherein the optical element is located on the first obverse-surface conducting region, and the second obverse-surface conducting region is located between the first obverse-surface conducting region and the inner surface of the reflector as viewed in the thickness direction,wherein the second obverse-surface conducting region is spaced apart from the inner surface of the reflector as viewed in the thickness direction, andwherein the obverse-surface conductive layer includes a third obverse-surface conducting region that is disposed between the first obverse-surface conducting region and the second obverse-surface conducting region as viewed in the thickness direction and that connects the first obverse-surface conducting region and the second obverse-surface conducting region.
