PROBLEM TO BE SOLVED: To provide a production method capable of high-speed film formation for the purpose of improving productivity by casting a solvent solution of a polyimide precursor on a support, and further improving productivity of a thin film And A polyimide solution in which a solvent solution of a polyimide precursor is cast on a support, the solvent in the solution is removed, the film is peeled from the support as a self-supporting film, and the self-supporting film is heated to imidize. A method for producing a film, A method for producing a polyimide film, comprising casting a solvent having compatibility with a polyimide precursor between a support and a solvent solution of a polyimide precursor to be cast.
