The present invention provides a functionalized polyimine substrate film which is capable of preventing foreign matter from entering into a polyimide film and having good peelability from a carrier film and having a functional layer on the polyimide film. Manufacturing method. A method for producing a polyimine substrate film with a functional layer, wherein a first solution is applied to a continuously supplied transport body to perform a first heat treatment, and then a second solution is applied to perform a second heat treatment, thereby obtaining A long-polyimine laminate having a first polyimide-hardened layer and a second polyimide-hardened layer, and then one of the polyimide-hardened layers is a polyimide film, and the other is One is a carrier film, a functional layer is formed on the polyimide film, and the carrier film is separated to obtain a polyimide film having a functional layer. |
