PROBLEM TO BE SOLVED: To provide a method for producing a reduced iron powder, which has adequate gas reaction efficiency and high productivity. SOLUTION: The method for producing the reduced iron powder includes: alternately stacking and filling a powdery reducing agent and a powdery iron oxide in a reaction vessel so that the powdery reducing agent is filled to form the bottom layer and the top layer; and heating the reaction vessel in a heating furnace and simultaneously blowing a hydrogen gas into the reaction vessel from the bottom part to reduce the powdery iron oxide.
