Claim:
1. A method for producing a Group III nitride semiconductor light-emitting device including a light-emitting layer having a MQW structure in which a plurality of layers units are repeatedly deposited, each layer unit comprising a well layer formed of Group III nitride semiconductor containing In, a GaN protective layer, and a barrier layer formed of Group III nitride semiconductor containing Al sequentially deposited, wherein the protective layer is grown at the same temperature as employed for the well layer, at a growth rate of larger than 0.5 times and not larger than 1.1 times the growth rate of the well layer through MOCVD on the well layer, so as to have a thickness of not less than 5 Å and not larger than 8 Å at the start of growth of the barrier layer being formed after the formation of the protective layer.
