A method for manufacturing an electroconductive pattern 40, provided with: a lamination step for laminating an acid generation film 10 containing an acid proliferation agent and a photoacid generator on a polymer film 20 containing an electroconductive polymer formed on a substrate 21; a masking step for masking the top of the acid generation film 10; a light irradiation step for irradiating the laminate from the acid-generation-film 10 side; a doping step for doping the electroconductive polymer with an acid generated and proliferated in the acid generation film 10 by the light irradiation; and a releasing step for releasing the acid generation film 10 from the polymer film 20. This method makes it possible to provide an electroconductive film and a method for manufacturing an electroconductive pattern in which photoacid generation and acid proliferation effects are utilized.
