PROBLEM TO BE SOLVED: To obtain a new material for electroluminescent element, having excellent emission characteristics, heat resistance and durability so as to give a new EL element having high emission luminance and high emission efficiency and excellent heat resistance and durability and an amorphous film using the same. SOLUTION: This material for electroluminescent element is represented by general formula (Ar<1> to Ar<4> are each an aryl group; n is a natural number). This amorphous film is obtained by heating and melting the material for electroluminescent element and standing the molten material to cool and coating a solution in a fixed thickness by a spin-coating method or by a film-forming method such as a vapor deposition method.
