| titleOfInvention | Method for producing multilayer polyimide film |
| abstract | Provided is a method for producing a multilayer polyimide film that can be suitably used for a high-frequency circuit board capable of reducing transmission loss. SOLUTION: A non-thermoplastic polyimide layer 2 having a dielectric loss tangent at 10 GHz of 0.001 to 0.009 is laminated on at least one surface of a non-thermoplastic polyimide film 1, and further a thermoplastic polyimide layer 3 is laminated, The manufacturing method which heat-processes so that a volatile matter amount may be 8 weight%-18 weight%, obtains a prefilm, heat-processes a prefilm, and obtains the multilayer polyimide film 4.
