Provided is a transparent conductive ink which contains metal nanowires and/or metal nanotubes as a conductive component and can form a coating film which has good conductivity and a high light transmittance property, and also provided is a transparent conductive pattern forming method wherein this transparent conductive ink is used for forming a transparent conductive pattern by simple production steps, to thereby suppress the production cost and environmental load. At least one of metal nanowires and metal nanotubes are dispersed in a dispersion medium containing a shape-holding material which contains an organic compound having a molecular weight in the range of 150 to 500 and which has a viscosity of 1.0×103 to 2.0×106 mPa·s at 25°C, to prepare a transparent conductive ink. A transparent conductive pattern is formed by printing a pattern having an arbitrary shape on a substrate using this transparent conductive ink, subjecting the pattern to a heating treatment to dry the pattern, and subjecting the pattern which has been dried to pulsed light irradiation.
