A metal film, particularly, a stainless steel film having been not subjected to roughing treatment, and an aromatic polyimide substrate film having a thermoplastic surface can be combined with a high bonding strength to form a metal film/aromatic polyimide film laminate, utilizing an amorphous aromatic polyimide film of 0.05 to 3 &mgr;m thick which has a glass transition temperature in the range of 200 to 300° C.
