NOVELTY - The method involves providing conductive carbon layer on both surface sides of substrate (2). An overcoat layer (3) is provided upon the conductive carbon layer provided on both surface sides of substrate. A resin layer (4) having a prescribed pattern is provided upon the overcoat layer provided on both surface sides of substrate. The conductive carbon layers are irradiated with UV radiation in accordance with openings in the resin layer under an atmosphere provided with oxygen.    USE - Method for forming film such as electrically conductive film and insulating film (all claimed) for substrate used for display panel of LCD, plasma display, organic electroluminescent display, touch-screen, and solar cell.    ADVANTAGE - The high-resolution electro-conductive film can be obtained easily.    DETAILED DESCRIPTION - The method involves comprising overcoat layer with the composition chosen from the groups of hydrolyzate of hydrolyzable organosilane. The thickness of overcoat layer is 1 nm - 1 mu m. The resin of the raw material which does not transmit UV ray is used, and the mask is provided as a resin layer by printing unit. The mask is closely adhered and provided in the overcoat layer. The wavelength of UV ray is in the range of 10-400 nm and 150-180 nm. The irradiation accumulated light quantity of UV ray is 50-500000mJ/cm2 and 500-30000mJ/cm2. The mask is removed after the UV irradiation is comprised. The oxygen pressure of the atmosphere is 101-21273 Pa and 1013-10130 Pa. The conductive carbon layer is comprised with grapheme and carbon nanotube. The conductive carbon layer is comprised by the single wall carbon nanotube for receiving the acid treatment. INDEPENDENT CLAIMS are included for the following:    (1) an electrically conductive film; and    (2) an insulating film.
