Abstract: An illuminator includes a first terminal, a second terminal, and a light emitting diode mounted on the first terminal and electrically connected to the second terminal. The light emitting diode includes a chip body, a lower electrode formed on a lower surface of the chip body, and an upper electrode formed on an upper surface of the chip body. The chip body includes an n-type semiconductor layer, a p-type semiconductor layer, and a light emitting layer interposed therebetween. The upper electrode is formed entirely over the upper surface of the chip electrode.
