Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing a reduced iron by which the reduced iron briquette having high average quality can be obtd in high productivity. SOLUTION: Iron oxide briquette containing carbonaceous material having almost 10-30 mm in the range of grain diameter, is laid on the furnace hearth of a shifting floor type heating furnace so that the laid density becomes =1200 deg.C within 1/3 of the staying time of this iron oxide briquette in the shifting floor type heating furnace. The, after making the reduced iron briquette by reducing until the metalloid ratio of the iron oxide briquette becomes >=85%, this reduced iron briquette is discharged from the moving floor type heating furnace.
