PROBLEM TO BE SOLVED: To provide a light-emitting diode mounting substrate which enables a change in a circuit configuration of a light-emitting diode without changing a size.SOLUTION: A mounting substrate 1 comprises: a first front electrode 12a1 which establishes continuity with a positive electrode 11b1 and establishes continuity with an anode of a first small LED 21 when the first small LED 21 is mounted; a second front electrode 12a2 which establishes continuity with a second back electrode 12b2 and establishes continuity with an anode of a second small LED 22 when the second small LED 22 is mounted; a third front electrode 12a3 and a fourth front electrode 12a4 which establish continuity with the positive electrode 11b1 and establish continuity with an anode of a large LED 31 when the large LED 31 is mounted; a fifth front electrode 12a5 which establishes continuity with a second back electrode 12b2 and establishes continuity with a cathode of the first small LED 21 when the first small LED 21 is mounted; and a sixth front electrode 12a6 which establishes continuity with a negative electrode 11b2 and establishes continuity with the anode of the second small LED 22 or the large LED 31 when the second small LED 22 or the large LED 31 is mounted. |
