The present invention provides a method for producing a Group III nitride semiconductor light-emitting device wherein a p-cladding layer has a uniform Mg concentration. A p-cladding layer having a superlattice structure in which AlGaN and InGaN are alternately and repeatedly deposited is formed in two stages of the former process and the latter process where the supply amount of the Mg dopant gas is different. The supply amount of the Mg dopant gas in the latter process is half or less than that in the former process. The thickness of a first p-cladding layer formed in the former process is 60% or less than that of the p-cladding layer, and 160Åor less. |
