Abstract: PROBLEM TO BE SOLVED: To provide a technique for preventing pin-removing failure in a polyimide-based multilayered film after burning in production of the same by a casting film formation method while enhancing the peelability of a multilayered gel film from a support even in the case that the peelability of the multilayered film from the support is enhanced by employing a chemical imidation method, and effectively avoiding the ply separation of the multilayered gel film. SOLUTION: In such a case that, for example, a multilayered liquid film 30 comprising thermoplastic polyimide varnish/heat-resistant polyimide varnish/thermoplastic polyimide varnish is formed on an endless belt and converted to the multilayered gel film 40, a liquid film 32 comprising the heat-resistant polyimide varnish is formed as a wide liquid film of which the width is wider than that of each of other liquid films 31 and 33, and both ends of the multilayered liquid film 30 are formed into a single-layered structure composed only of the wide liquid film. In this case, it is preferable to use a multilayered coextrusion die wherein an inner deckle is inserted in a flow channel. The multilayered gel film 40 may be burned in such a state that a tenter pin 17 is thrust in the end of the single-layered structure to fix it. COPYRIGHT: (C)2010,JPO&INPIT
