Abstract
A method for manufacturing a polyimide-metal laminate including forming a polyimide film, in which at least surfaces of both sides of the film are formed by thermally fusion-bondable polyimide layers (a), and thermal compression-bonding metal layers on both sides of the polyimide film; in which forming the polyimide film includes reacting a tetracarboxylic dianhydride component with a diamine component containing a diamine compound represented by general formula (1) to give a solution of a polyamic acid (a), forming a self-supporting film from the solution of the polyamic acid (a) and imidizing the self-supporting film by heating at a maximum heating temperature of 440° C. or lower to form the polyimide layer (a);
