Claim:
1. A polyimide metal laminated plate having: a first metal film; a first thermoplastic polyimide film laminated on a surface of the first metallic film; a first thermosetting polyimide film laminated on a surface of the first thermoplastic polyimide film distal from the first metallic film; and a second thermoplastic polyimide film laminated on a surface of the first thermosetting polyimide film distal from the first thermoplastic polyimide film; wherein: the first thermosetting polyimide film is prepared from a thermosetting polyimide precursor polymerized by a first diamine comprising p-phenylenediamine, a first dianhydride comprising pyromellitic dianhydride and 3,3′,4,4′-biphenyl tetracarboxylic dianhydride, and a first reactive monomer comprising polyoxypropylenediamine and 9,9′-bis(4-aminophenyl)fluorene; each of the first thermoplastic polyimide film and the second thermoplastic polyimide film is prepared from a thermoplastic polyimide precursor polymerized by a second diamine, a second dianhydride, and a second reactive monomer comprising 4,4′-(1,3-phenylenediisopropylidene)bisaniline; wherein based on the total amount of the thermosetting polyimide precursor, the amount of p-phenylenediamine of the first diamine is 25.05 wt %, the amount of pyromellitic dianhydride of the first dianhydride is 9.73 wt %, the amount of 3,3′,4,4′-biphenyl tetracarboxylic dianhydride of the first dianhydride is 59.09 wt %, the amount of polyoxypropylenediamine of the first reactive monomer is 2.67 wt %, and the amount of 9,9′-bis(4-aminophenyl)fluorene of the first reactive monomer is 3.46 wt %.
