To obtain a conductive film with high quality and aimed at improving productivity through restraint of generation of deformation defects due to wrinkles in case of carrying out of smoothing treatment by a calender roll.
A manufacturing method of the conductive film includes a metallic silver forming process 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 process 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 into the smoothing treatment process, and P2 represents a conveying force applied when the smoothing-treated conductive film is discharged from the smoothing treatment process.
