PROBLEM TO BE SOLVED: To provide a process for fabricating a light-emitting element in which the width of a current constriction region can be controlled when the current constriction region is formed based on an easy method. SOLUTION: The process for fabricating a light-emitting element comprises a step (A) for forming a first compound semiconductor layer 20 having a first conductivity type, an active later 30, and a second compound semiconductor layer 40 having a second conductivity type sequentially on a substrate 10, a step (B) for forming a plurality of spot holes 50 in the thickness direction at least in the region of the second compound semiconductor layer 40 located on the outside of a region for forming a current constriction region 44, and a step (C) for forming an insulating region 43 by performing insulation processing from the sidewall of the hole 50 for a part of the second compound semiconductor layer 40, thus obtaining a current constriction region 44 surrounded by the insulating region 43 in the second compound semiconductor layer 40.
