PROBLEM TO BE SOLVED: To provide a light-emitting device, which uses a plurality of light- emitting element, for compact size and improved color balance while drop of output and shortening of life are avoided. SOLUTION: Related to a light-emitting device 1, LED elements 3G and 3B comprising first and second electrodes 3a and 3b on a light-emitting surface side while the LED element 3B comprising the first electrode 3a on the light- emitting surface side, with the second electrode on a board 2 side, are alternately arrayed on a surface 2a of the board 2. Even when LED elements 3R, 3G and 3B are arrayed densely, connection with bonding wires 7R, 7G, 7B, 8G and 8B is easy, resulting in compact mounting. |
