The present invention provides a method for producing a high-quality film that is a thin film and has both excellent appearance and functionality, and the high-quality film. A polymer compound precursor or a polymer compound dissolved in a subcritical or supercritical fluid is sprayed and applied to the surface of an object to form a film. The surface roughness Rz obtained by curing the coating film and removing the undulation with a cut-off value of 8 mm is 0 with respect to the surface shape curve having a thickness of 20 μm or less and a contact type surface roughness meter. A step of forming a high-quality film having a thickness of 8 μm or less, wherein the coating conditions are controlled so that the viscosity immediately after the formation of the film is 10 to 300 mPa · sec. Forming method and coated product thereof. [Effect] By high-pressure carbon dioxide coating, it is possible to provide a high-quality coated product in which a coating having good smoothness and a surface roughness Rz of 0.8 μm or less is formed.
