Provided is a light emitting diode excellent in sealing performance, heat resistance, light extraction efficiency, light emission luminance, and the like. In a light emitting diode including a die bond, a light emitting element, and a sealing layer, the sealing layer includes zirconia fine particles surface-treated with an organic resin and an organosilicon compound, and the average of the surface-treated zirconia fine particles The secondary particle size (D M2 ) is in the range of 5 to 50 nm, the average primary particle size (D M1 ) is in the range of 5 to 50 nm, the average secondary particle size (D M2 ) and the average primary particle size (D M1) and the ratio of (D M2) / (D M1 ) is a light emitting diode, characterized in that in the range of 1-10.
