摘要

heat-fusible polyimide film and method of manufacturing the same, the heat-fusible polyimide film to provide a polyimide metal laminate used. A heat fusible polyimide film of a single layer obtained by polymerizing a tetracarboxylic acid dianhydride component and a diamine component, wherein the tetracarboxylic dianhydride component, 2,3,3 ', 4'- biphenyltetracarboxylic dianhydride and 3,3 ', and a 4,4'-biphenyltetracarboxylic acid dianhydride, the diamine component comprises an aromatic diamine compound of formula (I) as a main component . ## STR1 ## (wherein, X is O, CO, C (CH3) 2, CH2, SO2, S or a direct bond, may be different in each identical in the case of two or more binding modes, n is is an integer of 0~4)
