PROBLEM TO BE SOLVED: To provide a light-emitting device that allows high-density mounting by flip-flop mounting and has high reliability of the amount of light.SOLUTION: A wiring pattern 21 includes an anode pattern and a cathode pattern disposed with a predetermined distance from each other, and a pattern for parallel connection disposed between the anode pattern and the cathode pattern with a predetermined distance from both the patterns. On the anode pattern and the pattern for parallel connection, a plurality of light-emitting elements 10 are mounted so that anode electrodes are connected to the anode pattern and cathode electrodes are connected to the pattern for parallel connection. On the pattern for parallel connection and the cathode pattern, another plurality of light-emitting elements 10 are mounted so that anode electrodes are connected to the pattern for parallel connection and cathode electrodes are connected to the cathode pattern. Each of the light-emitting elements 10 is connected in series and parallel to the other adjacent light-emitting element by the wiring pattern 21. |
