PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element which has high brightness and high luminous efficiency; and provide a manufacturing method of the semiconductor light-emitting element.SOLUTION: A semiconductor light-emitting element comprises a light-emitting structure 10 including at least a semiconductor structure layer 15 composed of a first semiconductor layer 16 having a first conductivity type, a second semiconductor layer 18 having a second conductivity type and a luminescent layer 17 arranged between the first semiconductor layer and the second semiconductor layer. A surface of the light-emitting structure on the second semiconductor layer side serves as a light extraction surface. The light extraction surface has, on a surface thereof, an uneven structure 50 composed of cone-shaped or columnar projections each including a groove which extends from a top toward a bottom. |
