PROBLEM TO BE SOLVED: To provide a cheaper method of producing conductive inks that is used in a wide range of applications. SOLUTION: The method includes a step where a depositing solution is prepared, and the depositing solution is liquid-phase deposited onto a substrate 30, and the depositing solution is heated to a temperature lower than about 140°C, wherein the depositing solution is comprised of a mixture of first metal nanoparticles 10 and second metal nanoparticles 60 or a combination of first metal nanoparticles and a soluble second metal nanoparticle precursor, if the depositing solution is a combination of the first metal nanoparticles and the soluble second metal nanoparticle precursor, the method further includes a step where the soluble second metal nanoparticle precursor is heated to a temperature lower than 90°C before the heating to a temperature lower than about 140°C to destabilize the soluble second metal nanoparticle precursor and form the second metal nanoparticles 20, wherein the average diameter of the first metal nanoparticles is about 50-1,000 nm and the average diameter of the second metal nanoparticles is about 0.5-20 nm.
