Abstract
The film production method includes: forming an ink layer on the base substrate covering the surface of the base substrate, the ink layer including a solvent and a film-forming material dissolved in the solvent; blowing gas to the ink layer so that the solvent in the ink layer spreads towards the periphery of the base substrate; removing the solvent in the ink layer so that the film-forming material in the ink layer forms a film covering the surface of the base substrate.
