PURPOSE: A method for manufacturing a metal nanopowder by the submerged electric explosion is provided to maximize the diffusion efficiency in case of the manufacturing of a metal nanopowder. CONSTITUTION: A method for manufacturing a metal nanopowder by the submerged electric explosion comprises the step of using at least one selected from butanol, isobutanol, secondary butanol, tertiary butanol and butanediol as a liquid solvent in which the submerged explosion occurs. The metal nanopowder comprises a nickel metal nanopowder. A conductive paste composition is added to the liquid solvent. The conductive paste composition comprises an organic solvent for a conductive paste, and optionally a liquid organic binder.
