Light having little color inconsistency is effectively emitted with a simple structure achieving favorable productivity. A plurality of multi-color light emitting diodes 13a, 13b, 13c and 13d comprising a plurality of LED chips r, g, b, and w having different light emission colors is disposed on the same surface such that the light emitted by the plurality of the multi-color light emitting diodes is mixed and emitted in a illumination device, wherein at least one multi-color light emitting diode from among the plurality of multi-color light emitting diodes 13a, 13b, 13c and 13c is disposed while being rotated by a prescribed angle with reference to one other multi-color light emitting diode in such a manner that when translating the one multi-color light emitting diode so as to overlap with the one other multi-color light emitting diode, LED chips having the same light emission color do not overlap with each other. |
