PROBLEM TO BE SOLVED: To provide a light-emitting diode board having light-emitting pellets arranged accurately on a line on a resin substrate. SOLUTION: A diode board 10 is so constituted that light-emitting diode pellets 2 with light-emitting areas 21 are arranged nearly in a row in a longitudinal direction of a long resin substrate 1 and biased to one side from a center in a breadthwise direction of the substrate 1. When the light-emitting diode pellets 2 are placed, the substrate 1 is warped within a plane. Or, the light- emitting diode pellets 2 are arranged in a shape of a curve. Therefore, when the light-emitting diode pellets 2 are set with heat, the pellets 2 come to be arranged on a straight line accurately. |
