PROBLEM TO BE SOLVED: To provide a multilayer polyimide film able to be laminated with a metal foil on a comparatively mild condition, a durability to chlorine containing solvents is superior, also able to select adhesion conditions by being able to control its glass transition temperature in a wide range and also endure for using at a high temperature and to provide a laminated body with a metal layer made by using the film. SOLUTION: A multilayer polyimide film made adjusted by changing a composition of p-phenylene dimaine and/or diaminodiphenylether so as a glass transition temperature (Tg) of a thin layer polyimide(Y) to be made a desired value in a range between 210°C and 310°C, the thin layer polyimide (Y) with an imide unit comprised of an aromatic tetracarboxylic acid dianhydride residue and am aromatic diamine residue being laminated to be one body on at least one side of a substrate polyimide (X) layer with a low thermal expansion nature and a metallic layer laminated bocy made by using the multilayer polyimide film.
