A light emitting device includes a light emitting element; a sealing resin covering the light emitting element; and a light diffusing material contained in the sealing resin. When a difference in refractive index at 10° C. between the sealing resin and the light diffusing material is Δn1 and a difference in refractive index at 50° C. between the sealing resin and the light diffusing material is Δn2, a ratio of Δn2 to Δn1 is in a range of 95% to 105%.
