Abstract

Disclosed is a method for producing a conductive film, which includes a silver metal forming step for forming a silver metal portion by exposing and developing a photosensitive material which has a silver salt-containing layer containing a silver salt on a supporting body, and a smoothing step for smoothing the silver metal portion. The smoothing step is performed by calender roll at a line pressure of not less than 1960 N/cm (200 kgf/cm). Consequently, the surface resistance of the film after development can be reduced in production of a conductive film which is effective for shielding electromagnetic waves.
