Method for producing conductive film

A method for producing a conductive film, comprising

• a metallic silver forming step of exposing and developing a photosensitive material comprising a long support and thereon an emulsion layer containing a silver salt, 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, wherein
• the support has a thickness of 95 μm or more,
• the conductive film precursor is pressed by a first calender roll and a second calender roll facing each other in the smoothing treatment,
• the first calender roll is a resin roll and is brought into contact with the support, and
• 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 where the smoothing treatment step is conducted.
