Abstract

A conductive film producing method includes a metallic silver forming step of exposing and developing a photosensitive material having a 95-μm-thick long support and thereon a silver salt-containing emulsion layer, thereby forming a metallic silver portion to prepare a conductive film precursor, and a smoothing treatment step of subjecting the conductive film precursor to a smoothing treatment to produce a conductive film. In the smoothing treatment, the conductive film precursor is pressed by first and second calender rolls facing each other, and the first calender roll is a resin roll to be brought into contact with the support. The method satisfies the condition of 1/2≦P1/P2≦1, wherein P1 represents a conveying force applied when the conductive film precursor is introduced to an area where the smoothing treatment step is conducted, and P2 represents a conveying force applied when the smoothing-treated conductive film is discharged from the area.
