A method for manufacturing an electroconductive film includes a liquid composition preparation step for preparing a liquid composition including an electroconductive agent, an elastomer, and a solvent, the electroconductive agent having thinned graphite in which layers of graphite are thinned and which has a bulk density of 0.05 g/cm3 or lower; a delamination treatment step for performing interlayer delamination of the thinned graphite by pressurizing the liquid composition and passing same through a nozzle; and a hardening step for coating a substrate with the delamination-treated liquid composition and hardening a coated film. According to the method, thinning of the graphite processes sufficiently and the thinning process can be performed in shorter time than conventionally possible, and makes it also possible to manufacture an electroconductive film that has high electroconductivity and has electrical resistance unlikely to increase even after repeated extension.
