Abstract
Provided is a transparent conducting film containing metal nanowires, the conducting film having a preferable optical property, electrical property, and having almost no in-plane resistance anisotropy. A method for producing a transparent conducting film provided with a conducting layer containing a metal nanowire and a binder resin, comprising steps of: preparing a coating liquid containing the metal nanowire and the binder resin, and coating the coating liquid on one main face of a transparent substrate, the coating step being performed by a bar-coater with a bar which has a bar surface constituted by a material having a friction coefficient of 0.05 to 0.45, wherein when the coating liquid is coated on one main face of the transparent substrate by the bar, a relative moving velocity (coating velocity) V (mm/sec) of the transparent substrate relative to the bar satisfies 2000≥V≥350, a groove formed on the bar has a pitch (P) and a depth (H) which satisfy a ratio P/H of 9 to 30, and on the bar surface, the groove is formed to be inclined in a way so that an angle between the longitudinal direction of the bar and a direction that the groove is formed is in a range of 60° to 88°.
