Provided is a light emitting device in which at least one of a light distribution angle and a luminous flux is increased and the productivity is excellent. A light-emitting device includes a light-emitting element, a phosphor layer that covers the light-emitting element, and an optical transfer layer that is disposed on the phosphor layer. When the refractive index of the phosphor layer 4 is n 1 and the refractive index of the light transfer layer 6 is n 2 , n 2 / n 1 ≦ 1.07 and at least 1 passing through the central axis of the phosphor layer 4 In one plane, the length from the central axis to the side surface of the phosphor layer 4 is d, and the total thickness of the phosphor layer 4 and the light transfer layer 6 excluding the thickness of the light emitting element 3 is t. When t / d> 0.4. [Selection] Figure 1 |
