PROBLEM TO BE SOLVED: To provide a laminate film which is invented in order to solve problems of the conventional inventions, which is obtained by adjacently uniting layers of base materials each having a low melting point, particularly a polyester resin and a soluble and transparent polyimide resin, to each other and the various properties such as transparency, heat resistance and mechanical properties of which are improved. ! SOLUTION: The laminate film has the polyester resin layer and the polyimide resin layer at the least. The polyimide resin layer is colorless, transparent and soluble in a solvent. The problems of the conventional inventions are solved by using the laminate film obtained by adjacently uniting the polyester resin layer and the polyimide resin layer to each other. !
