PROBLEM TO BE SOLVED: To provide a semiconductor light emitting element, which can be made having a semiconductor light emitting element consisting of one kind of material as a base by simple method, and by which the light emission of various tints including white and middle colors can be obtained, and an epitaxial wafer at low prices. SOLUTION: In the semiconductor light emitting element where at least a lower clad layer 3 of the first conductivity type, a luminous layer 4 smaller in band gap energy than that of the lower clad layer, an upper clad layer 6 of the second conductivity type larger in band gap energy than that of luminous layer are stacked on a substrate 1, a semiconductor layer including one or more kinds of rare earth elements is inserted into a side upper or a side lower than the above luminous layer 4, and the rare earth element doped in this insertion layer 5 produces fluorescence, being excited by the light emitted from the above luminous layer 4. |
