Zusammenfassung:	Provided is a method of producing a film excellent in external quantum efficiency when used in a light emitting layer of a light emitting device.A film production method comprisingan ink preparation step of preparing an ink comprising a specific metal complex,an ink storage step of storing the ink prepared in the ink preparation step for 3 days or more under light shielding, anda film formation step of forming a film by an application method using the ink stored in the ink storage step and in which the total content of metal complexes having a molecular weight larger by 16, 32 or 48 than that of the specific metal complex according to the area percentage value determined by liquid chromatography is 0.6 or less when the content of the specific metal complex according to the area percentage value determined by liquid chromatography is taken as 100.
