Abstract
A light emitting device includes a first resin layer which is made of transparent resin and provided outside a solid-state light-emitting element mounted on a mounting substrate; and a second resin layer which is provided outside the first resin layer and made of transparent resin that contains a phosphor which is excited with a luminescence wavelength of the solid-state light-emitting element, wherein when the refractive index of the solid-state light-emitting element is set to be N1, the refractive index of the first resin layer is set to be N2, and the refractive index of the second resin layer is set to be N3, the relationship of N1≧N2≧N3≧1 is established.
