PROBLEM TO BE SOLVED: To provide a light-emitting device the light distribution characteristics of which can be changed.SOLUTION: The light-emitting device includes a light-emitting element having a first surface to emit light, a translucent part provided on the first surface, and a light distribution control part provided on the periphery of the first surface and having a refractive index lower than that of the translucent part. The light distribution control part has light transmissivity. |
