<P>PROBLEM TO BE SOLVED: To provide a polyimide film which, especially when superposed on a metal layer by the laminating method, has the function of diminishing the thermal distortion to be imposed on the material; an adhesive film and a flexible metal-clad laminate each using the polyimide film. <P>SOLUTION: The polyimide film is obtained by reacting an aromatic diamine with an aromatic acid dianhydride and imidizing the polyamic acid obtained, and has a storage elastic modulus in a specific range. There are also provided the adhesive film and the flexible metal-clad laminate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
