To provide a method for manufacturing a surface light-emission laser element of low cost, by suppressing variation in element characteristics caused by dispersion in size of current constricted region.
Relating to a method of manufacturing a surface light-emission laser comprising such configuration as having a partial high-resistance so oxidized as to constriction an injection current to an active layer 3, a multi-layer film is grown on a substrate 1, and an oxide layer 5 is provided near the active layer 3, then an anti-oxidation layer 7 is selectively formed only in a light- emission region on the oxide layer 5, then the entire is oxidized to selectively oxidize only an exposed part of the oxide layer 5, and then a multi-layer film is grown for forming a current constriction structure.
