Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyimide film excellent in easily slidable property, capable of reducing the close adhesion of films with each other at a hinge part on laminating many layers of substrate plates by a hot press, and also dissolving a "sounding" trouble caused by the rubbing of the films with each other. SOLUTION: This method for producing the easily slidable polyimide film is provided by treating the surface of the polyimide film with a grinding tape to form streak-like unevenness on the film surface.
