The light emitting device comprising: a light-emitting element; a covering resin covering the light-emitting element; a wavelength converting material contained in the covering resin; and a light diffusing agent contained in the covering resin, wherein the light diffusing agent contains glass particles, a first refractive index n1 of the covering resin at a peak wavelength of the light-emitting element at 25 °C is in a range of 1.48 to 1.60, a second refractive index n2 of the covering resin at the peak wavelength at 100 °C is at least 0.0075 lower than the first refractive index n1, and a third refractive index n3 of the light diffusing agent at the peak wavelength of 25 °C is higher than the first refractive index n1. |
