To provide a copper and/or copper oxide dispersion capable of forming an electroconductive film exhibiting excellent stability with respect to temporal change and having a fine pattern form, an electroconductive film laminate obtained by laminating the electroconductive film produced using the copper and/or copper oxide dispersion, and an electroconductive film transistor. The copper and/or copper oxide dispersion contains 0.50-60 mass% of copper and/or copper oxide microparticles and the following components (1)-(4): (1) a surface energy modifier; (2) an organic compound having a phosphate group; (3) 0.050-10 mass% of a solvent having a vapor pressure of 0.010 Pa to less than 20 Pa at 20°C; and (4) a solvent having a vapor pressure of 20 Pa to 150 hPa at 20°C. The electroconductive laminate is obtained by laminating an electroconductive film containing copper on a substrate.
