The light emitting device comprises a substrate ( 2 ), a positive electrode ( 6 ) and a negative electrode ( 4 ) formed on the substrate ( 2 ), a light emitting diode ( 8 ) connected to the positive electrode ( 6 ) and the negative electrode ( 4 ), the transparent resin ( 12 and 14 ) that covers the light emitting diode ( 8 ), a fluorescent material ( 16 ) that absorbs at least part of light emitted by the light emitting diode ( 8 ) and converts it to light of longer wavelength, and the lens that changes the direction of light emission from the light emitting diode ( 8 ) and/or the fluorescent material ( 16 ). The resin ( 12 and 14 ) includes the fluorescent material ( 16 ) and is formed so as to constitute the lens of substantially semi-cylindrical shape, and the fluorescent material ( 16 ) included in the resin ( 12 and 14 ) is distributed with a higher concentration in a region near the surface of the light emitting diode ( 8 ) than in a region near the surface of the portion that constitutes the lens. |
