NOVELTY - The method involves forming an electric charge transport layer i.e. positive hole injection layer (3), by drying function. Another electric charge transport layer i.e. positive hole transport layer (4), is formed by crosslinking function such that ionization potential of a charge-transporting polymer with a cross-linkable group is identified with an electron-accepting compound i.e. organic onium salt. The former transport layer is provided with a charge-transporting compound and the electron-accepting compound, where molecular weight of the charge-transporting compound is 5000 or less.    USE - Method for manufacturing an organic electronic device i.e. organic electroluminescent element, utilized for an organic electroluminescence display or organic electroluminescent illumination. Can also be used for manufacturing organic transistor, organic solar cell element, organic light emission transistor, organic magnetism device, organic diode, organic actuator and organic sensor e.g. pressure sensor, temperature sensor and humidity sensor.    ADVANTAGE - The method enables forming an electron carrying layer between a light emitting layer and an electron injection layer, thus improving luminous efficiency of the organic electroluminescent element. The method enables ionization potential of the charge-transporting polymer having cross-linkable group to be identified with the electron-accepting compound, so that diffusion of the electron-accepting compound to the latter electric charge transport layer can be reduced.
