Patent ID: 8836204

Claim:
An organic EL illumination device including an organic EL element, a plurality of anode terminal electrodes, and a plurality of cathode terminal electrodes on a glass substrate, the anode terminal electrodes and the cathode terminal electrodes used to evenly supply a current to the organic EL element, characterized in that the organic EL element has a polygonal shape, the numbers of the anode terminal electrodes and the cathode terminal electrodes are the same as the number of corners of the organic EL element, the anode terminal electrodes and the cathode terminal electrodes are alternately arranged along an outer periphery of the organic El element while being spaced away from one another, a length of a portion of each of the anode terminal electrodes facing the outer periphery of the organic EL element is longer than a length of a portion of each of the cathode terminal electrodes facing the outer periphery of the organic EL element, and the organic EL illumination device comprises a wiring board in which a circuit having anode electrodes corresponding to positions of the respective anode terminal electrodes and a circuit having cathode electrodes corresponding to positions of the respective cathode terminal electrodes are formed.
