Abstract: Disclosed is a technique for producing carbon-containing reduced iron in a direct reduction process, by cooling iron metal resulting from a reduction step while increasing the carbon concentration of the iron metal. This method for producing carbon-containing reduced iron includes a reduction step in which a reducing gas is brought into contact with a raw iron oxide material to obtain iron metal, and a cooling step in which the iron metal is cooled. The cooling step comprises a first step in which, after the reduction step, methane gas is brought into contact with the iron metal to carbonize the iron metal, a second step in which, after the first step, CO gas is brought into contact with the iron metal to carbonize the iron metal, and a third step in which, after the second step, methane gas or an inert gas is brought into contact with the iron metal.
