    • PROBLEM TO BE SOLVED: To provide a light emitting element which is superior in uniformity of brightness and efficiency in taking out light, with a wide selection band of optical wavelength which causes optical scattering. SOLUTION: The light emitting element includes a light emitting part and a microstructure film. The microstructure film has a surface parallel to the light emitting surface of the light emitting element. A micropore in which an average aperture is 5-1,000 mm, an average pore density is 1×10 6 -10 10 /mm 2 , and a regulation degree defined by the following equation (i) is ≥50%, is formed on the surface parallel to the light emitting surface of the light emitting element: equation (i): regulation degree (%)=B/A×100. In this equation (i), A represents the total number of micropores within a measurement range, and B represents the number of centroids within such measurement range of a micropore as contains six centroids of micropores other than the micropore inside a circle when the circle is drawn having the centroid of the micropore as the center, having the shortest radius while inscribing to the edge of other micropore.
