Summary:PROBLEM TO BE SOLVED: To provide metal powder which is fine and has excellent dispersibility, and also has reduced coarse flocculated grains, and to provide a method for producing the same. SOLUTION: The production method comprises: a stage where raw material slurry comprising metal grains and water is obtained by wet reduction reaction or a water atomizing process; and a stage where the slurry adjusted so that the concentration of the metal grains in the raw material slurry reaches 100 to 1,000 g/L is charged to a drier, and is dried under the conditions where the reduction rate of the moisture content in the slurry is controlled to 0.3 to <10,000 mass%/min.
