NOVELTY - The method involves coating dispersion liquid in which polymer includes electro-conductivity. Secondary polymers are provided with infrared ray absorbing property dispersed to water-system solvent on transparent base material (2). A conductive layer is formed by an infrared heater included by performing infrared irradiation with respect to the coated dispersion liquid. Infrared rays are absorbed by another polymer, where wavelength of the infrared rays is 2.5-3.0 micrometers. The infrared rays are irradiated by the infrared heater.    USE - Method for manufacturing an electrically conductive film i.e. transparent conductive film, utilized in an organic electronic device i.e. organic electroluminescent element and touch-screen (all claimed), utilized in a ATM of a financial institution i.e. bank, an automatic vending machine, an automatic ticket vending machine, a mobile telephone, a flat-panel TV, a portable information terminal (PDA), a digital audio player, a handheld game machine, a copy machine, a facsimile machine, a car-navigation apparatus and a digital-information apparatus. Can also be used for manufacturing an electrically conductive film utilized in an LCD element, an organic light emitting element, an inorganic electroluminescence element, an electronic paper, an organic solar cell, an inorganic solar cell, an electromagnetic wave shield, an electroluminescent light control element, an indispensable technical element, a self-illuminating type display, a backlight for liquid crystals and an illumination system.    ADVANTAGE - The method enables forming the conductive layer by the infrared heater included by performing infrared irradiation with respect to the coated dispersion liquid such that the infrared rays can be absorbed by the polymer in which the wavelength of the infrared rays is 2.5-3.0 micrometers and the infrared rays can be irradiated by the infrared heater, so that transparency and electro-conductivity of the electrically conductive film can be improved, while suppressing deformation of the base-material.
