Provided are a thiol group-containing colored compound that allows manufacture of a transparent conductive film that can prevent scattering of external light and has a small sheet resistance by adsorbing the colored compound on a metal nanowire body without dissolving the metal nanowire body (surface treating the metal nanowire body with the colored compound), thereby allowing manufacture of an information input device and an electronic apparatus that can improve anti-black floating properties (bright room contrast) and electrode pattern invisibility, and metal nanowires that are surface treated with the thiol group-containing colored compound, a dispersion liquid that contains the metal nanowires, a transparent conductive film that contains the metal nanowires, an information input device that includes the transparent conductive film, and an electronic apparatus that includes the transparent conductive film. The thiol group-containing colored compound includes a chromophore having absorption in a visible light region, a thiol group, and a spacer provided between the chromophore and the thiol group. The spacer is a chain alkylene group having 2 to 30 carbon atoms, a cyclic alkylene group having 3 to 30 carbon atoms, or a derivative of either alkylene group in which the number of carbon atoms in an additional structure of the alkylene group is equal to or less than the number of carbon atoms in the alkylene group.
