A transparent electroconductive film having a low resistivity is provided. In a film-forming method of the present invention, a transparent electroconductive film is formed on a surface of a substrate by sputtering, in a vacuum atmosphere, a target in which ZnO is a main component and Al2O3 and B2O3 are added, and then the transparent electroconductive film is annealed by the heating thereof at a temperature of 300° C. or more and 400° C. or less. The resistivity of the obtained transparent electroconductive film is reduced because the film has ZnO as the main component and Al and B added thereto. The transparent electroconductive film formed by the present invention is suitable as a transparent electrode for the FDP, etc.
