PURPOSE:To provide a high molecular LB film electric element with excellent dynamic strength, heat resistance, etc., by a method wherein polyfumarate is melted into a solution of organic solvent of 0.1-3 mg/ml to be deposited as monomolecular solid films with surface pressure of 10-30 dynes/cm. CONSTITUTION:Polyfumarate with rigid side chain not to be formed into a yarn ball type association body due to bar type molecular state is melted into a water soluble organic solvent not exceeding 10 mg/ml preferably in concentration of 0.1-3 mg/ml to be slowly developed on a clean level for evaporation forming a gas film with surface pressure not exceeding 1 dyne/cm in order to control the molecular orientation, surface smoothness, homogeneity, etc., of film. Finally, molecular solid films formed by controlling the surface pressure decided by depressing in the level direction per categoty are deposited on a solid substrate by a vertical immersion process or horizontal bonding process.
