It is an object of the present invention to provide a method for manufacturing a light-emitting element in which decrease over time in emission efficiency of the light-emitting element having a structure in which an organic compound is sandwiched between a pair of electrodes is suppressed and long-life thereof can be enhanced. It is a method for manufacturing a light-emitting element having a plurality of layers composed of an organic compound between a pair of electrodes, wherein a processing to expose to an atmosphere including oxygen is performed after or before forming at least one layer of the plurality of layers. Note that the plurality of layers includes a light-emitting layer, and is composed of the light-emitting layer and at least one or more layers selected from a hole injecting layer, a hole transporting layer, a hole blocking layer, an electron transporting layer, and an electron injecting layer.
