PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element capable of achieving wider bandwidth despite its high output.SOLUTION: A semiconductor light-emitting element 1 comprises a p-type semiconductor layer 20, an n-type semiconductor layer 10, and an active layer 30 which are composed of a gallium-arsenide-based material. The active layer 30 is arranged between the n-type semiconductor layer 10 and the p-type semiconductor layer 20, and includes a multiquantum well structure in which a plurality of well layers 31 to 34 and a plurality of barrier layers 35 to 39 are alternately laminated. Wavelengths of light emitted from the well layers 31 to 34 differ per well layer. A quantum level of each well layer has only a first quantum level. |
