PURPOSE: To obtain a polyazomethine improved in the ability to transport electrons, the ability to emit electroluminescence, the ability to transport holes, heat resistacne and durability by reacting a specified diamino compound with a specified dialdehyde compound. CONSTITUTION: A substrate 22 is set within the vacuum deposition chamber 21 of a vacuum deposition apparatus 20, a diamino compound of formula I (wherein X is an aromatic hydrocarbon group or a group derived from a heterocyclic compound) and a dialdehyde compound of formula II (wherein Y is a group having an aromatic tert. amine skeleton), both of which are used as polymerizable monomers, are placed in their respective vapor deposition sources 23a and 23b. The chamber 21 is evacuated until the inside pressure decreases to 10<-2> Pa or below, while the temperature of the deposition surface of the substrate 22 is adjusted to -50 to 200 deg.C. After the pressure inside the chamber 21 reaches a specified value, the temperatures of the vapor deposition sources 23a and 23b are adjusted to -10 to 500 deg.C so that the monomers may be vaporized in a molar ratio of the diamino compound to the dialdehyde compound of 1:(1-30), and that the deposition film may be formed at a rate of deposition of 0.1-10Å/sec. Thus, a deposition film of a polyazomethine of formula II is formed on the substrate 22.
