The present invention provides a solution increasing illuminance of the irradiation surface in a vicinity of the optical axis and suppressing the generation of the yellow ring phenomenon. The present invention is for a light emitting device 1 having a light emitting element 2 and a light control member 3, the light control member has a light incident surface 31 and light emitting surface 32, when the intersection point of the optical axis and a light emitting surface of the light emitting element 2 is defined as a base point, an angle formed by the optical axis and a line connecting the base point and an optional point is defined as α1, and distance between the optional point of the light incident surface and the base point is defined as D1, for the light incident surface, the distance D1 is increasing as increasing the angle α1 if the angle α1 is 0≦α1
