PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element suitable to high luminance.SOLUTION: A semiconductor light-emitting element includes: a first semiconductor layer of a first conductivity type which is formed on a first electrode; second semiconductor layers 17, 18 of a second conductivity type different from the first conductivity type which are arranged on the first semiconductor layer, have a first irregularity part on the surface opposite to the first semiconductor layer side; an active layer which is formed between the first semiconductor layer and the second semiconductor layers; and a second electrode 3 which is formed in close contact with the surface having the first irregularity part on the second semiconductor layers, has a second irregularity part corresponding to the first irregularity part, having the difference of elevation smaller than that between the apex of the salient and the bottom of the recess of the first irregularity part, and having the salient with the curved apex on the surface opposite to the second semiconductor layer side, and transmits light emitted by the active layer.SELECTED DRAWING: Figure 3 |
