PROBLEM TO BE SOLVED: To provide a method for inexpensively producing reduced iron by utilizing a technique with which a mixture containing an iron-containing material and a carbonaceous solid reducing agent, is simply agglomerated without bringing about high cost. SOLUTION: When the reduced iron is produced by supplying the agglomerate of the mixture containing the iron-containing material and the carbonaceous solid reducing agent onto a shifting floor shifted in a heating furnace and heating and reducing the agglomerate; as the carbonaceous solid reducing agent contained in the agglomerate, the one having≥65 HGI(Hardgrove Grindability Index) value in the grindability standard test for coal regulated in JIS M8801, is used and also, the agglomerate agglomerated with only water without adding a binder, is used to produce the reduced iron.
