PROBLEM TO BE SOLVED: To obtain a polyimide film that has excellent running properties, adhesiveness and dimensional stability of a film and is applicable to an automatic optical inspection system (AOI) of a flexible printed circuit board (FPC) or a chip-on-film (COF) and to provide a method for producing the same. SOLUTION: The polyimide film is produced mainly by imidation from p-phenylenediamine and 4,4'-diaminodiphenyl ether as diamine components and pyromellitic acid dianhydride as an acid dianhydride component and comprises 0.1-0.9 wt.% based on the weight of a film resin of inorganic particles, having particle diameters in a range of 0.01-1.5μm, an average particle diameter of 0.05-0.7μm and a particle size distribution in which≥80 vol.% based on the total particles of inorganic particles having particle diameters of 0.15-0.60μm, dispersed into the film.
