A method produces a high-strength sintered ore while maintaining a high production rate by performing appropriate oxygen enrichment at a position closer to an ore discharging section than an ignition position without using gaseous fuel in the operation of a sintering machine. In a method for producing sintered ore including sequentially combusting carbonaceous material in a sinter bed (raw material charged layer) in a DL sintering machine to sinter the mixed raw material, in performing oxygen enrichment from above the raw material charging layer on the sintering machine, the oxygen enrichment is performed at a position closer to the ore discharging section than the position where 4 minutes have passed since the upper surface of the charging layer was ignited
