1. A light emitting device comprising:

  • a substrate;

    a plurality of LED chips positioned around a center of a primary surface of the substrate;

    a resin frame made of resin that has light reflectivity, formed on the primary surface of said substrate and provided annularly so as to surround a mounting area in which said plurality of LED chips are provided;

    an anode-side electrode land and a cathode-side electrode land which are electrodes to be connected to an external voltage supply of said light emitting device, the anode-side electrode land and the cathode-side electrode land being provided outside said resin frame;

    an electrode wiring pattern formed on the primary surface of said substrate including (i) an anode pattern extending from said anode-side electrode land to a portion under said resin frame and(ii) a cathode pattern extending from said cathode-side electrode land to another portion under said resin frame, so as to electrically connect the plurality of LED chips to the anode-side electrode land and the cathode-side electrode land; and

    a protection film provided on the anode pattern and the cathode pattern.
