Provided is a light emitting device that includes a concavo-convex structure mainly utilizing the diffraction effect rather than the scattering effect of light, thereby improving the light extraction efficiency. A light emitting device includes a laminated part 8 where a semiconductor layer including a light emitting layer 84 is laminated, and a diffraction surface 2 comprising a concavo-convex structure which is formed at a boundary of any layer in the laminated part 8, and which reflects incident light emitted by the light emitting layer 84 in accordance with a Braggs diffraction condition. The concavo-convex structure is formed in such a way that an inclination of a side wall of a convexity relative to the diffraction surface 2 is greater than 75 degrees.
