An object of the present invention is to manufacture a white light-emitting diode element by coating a blue light-emitting diode chip with a coating of a synthetic resin containing a fluorescent material. The object is achieved by bonding an LED material plate corresponding to a plurality of LED chips to an expansion sheet, dividing the LED material plate into individual LED chips, stretching the expansion sheet to widen the spacing between the LED chips, forming a synthetic resin layer between the chips, and dicing the synthetic resin layer to remove portions of the synthetic resin layer between the LED chips while leaving part of the synthetic resin layer on a side surface of each of the LED chips.
