PROBLEM TO BE SOLVED: To provide a light-emitting device having small changes in a luminescent color even when a temperature has changed.SOLUTION: A light-emitting device has: a light-emitting element; a coating resin covering the light-emitting element; a wavelength conversion material contained in the coating resin; and a light diffusion material contained in the coating resin. The light diffusion material contains glass particles. A first refractive index n1 at 25°C at a peak wavelength of the light-emitting element of the coating resin is 1.48 or more and 1.60 or less. A second refractive index n2 at 100°C at the peak wavelength of the light-emitting element of the coating resin is lower than the first refractive index n1. A refractive index difference between the first refractive index n1 and the second refractive index n2 is 0.0075 or more. A third refractive index n3 of the light diffusion material at 25°C is higher than the first refractive index n1.SELECTED DRAWING: Figure 4B |
