Abstract: A method for producing metal nanowire of small diameter and long length. In the method for producing a metal nanowire, a first solution containing an ionic derivative and a polyol as a solvent are kept at 80-200° C., and a second solution containing a metal salt and a polyol as a solvent is supplied into the first solution so that the ratio between the number of moles of metal atoms in the metal salt supplied in one minute and the total number of moles of halogen atoms in the ionic derivative in the first solution (the number of moles of metal atoms in the metal salt supplied in one minute/the total number of moles of halogen atoms in the ionic derivative) is less than 10. It is preferable that the ionic derivative is a quaternary ammonium halide and the metal salt is silver nitrate.

Abstract: Methods for producing a transparent conductive film and transparent conductive pattern having superior in-plane uniformity of resistance, by a printing method of slit coating or roll coating of metal nanowire ink. The methods include applying a metal nanowire ink containing metal nanowires, a binder resin containing more than 50 mol % monomer units derived from N-vinylacetamide, and a solvent, to at least one surface of a transparent resin film and drying to form a transparent conductive layer, the application of the metal nanowire ink to the transparent resin film being application by slit coating or roll coating performed using a transparent resin film and metal nanowire ink with which the advancing angle (θa) of the dynamic contact angle of the metal nanowire ink relative to the transparent resin film satisfies 10.0°
