To provide a light-emitting device that has a lens for controlling the distribution of light, and phosphor dispersed near a light-emitting diode, is manufactured easily, and prevents contamination from being taken into a sealing resin.
A light-emitting element has: 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 sealing resin 14 for covering the light-emitting diode 8; the phosphor 16 for converting at least one portion of the luminescence of the light-emitting diode 8 to a longer wavelength; and a lens for changing the light distribution direction of the luminescence of the light-emitting diode 8 and/or the phosphor 16. The sealing resin 14 contains the phosphor 16 and is integrally formed so that it composes the lens. The phosphor 16 is distributed with high density near the surface of the light-emitting diode 8 as compared with an area near the surface of the sealing resin 14.
