CONDUCTIVE FILM, METHOD FOR PRODUCING SAME, AND TOUCH PANEL

摘要

Provided are: a method for producing a conductive film having excellent conductivity, excellent transparency and low haze, while being reduced in pimple defects, said method being capable of successfully dispersing metal nanowires without aggregation during a coating operation; a conductive film which is produced by the above-described method for producing a conductive film; and a touch panel which comprises the conductive film. This method for producing a conductive film comprises: a cleaning step wherein a metal nanowire dispersion liquid that contains metal nanowires having an average minor axis length of 150 nm or less and a dispersant, said metal nanowires serving as metal particles, is cleaned by ultrafiltration with use of an ultrafiltration membrane; and a coating step wherein a coating liquid for conductive film formation, which contains the metal nanowire dispersion liquid after the cleaning step, is applied over a supporting body. This method for producing a conductive film is characterized in that the content of the dispersant in the metal nanowire dispersion liquid after the cleaning step ({mass of dispersant/(total mass of metal particles + mass of dispersant)} × 100) is 3.2% by mass or more.
