Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyimide film, wherein the surface flaw of the film due to foreign matter formed by the modification of an oligomer is improved, and a method for manufacturing the same. SOLUTION: The number of foreign matters with the maximum length of 1 mm or less due to the adhesion of a modified solid of an oligomer on the surface of a polyimide film is 6.0×10-3/m-2 or less.
