Abstract
A method for producing a light-emitting device includes oxidizing a current confinement layer containing Al by steam oxidation from a side face of a light-emitting element portion including the current confinement layer to form a current confinement structure in the light-emitting element portion; heating the light-emitting element portion to about 150° C. or higher and about 400° C. or lower at reduced pressure for a predetermined heating time while the oxidized current confinement layer is exposed at the side face; and after the light-emitting element portion is heated, forming a protective film on the side face.
