A number of red LEDs, green LEDs, and blue LEDs are mounted on one surface of a multilayer flexible substrate having a round plane figure. The LEDs are connected in series according to color. At least three sets of terminals which are each made up of a red feeder terminal, a green feeder terminal, a blue feeder terminal, and a common feeder terminal are provided on the periphery of the flexible substrate. Wiring patterns for connecting LEDs at the high-potential end of the red, green, and blue series-connected LEDs respectively to the red feeder terminals, the green feeder terminals, and the blue feeder terminals are provided to the flexible substrate. Also, a wiring pattern for connecting LEDs at the low-potential end of the red, green, and blue series-connected LEDs all to the common feeder terminals is provided to the flexible substrate.
