PROBLEM TO BE SOLVED: To provide a method for manufacturing sintered ore by which uneven sintering can be prevented with more certainty by using a DL type sintering machine and controlling, with higher precision, raw material charging density in a pallet-width direction without excessively increasing installation costs and maintenance costs. SOLUTION: A cutoff gate 4 and a compacting roller 5 are placed, in this order, between an ore-feed part 1 and an ignition furnace 2. The cutoff gate 4 is divided into a plurality of split plates 4a to 4h along the pallet-width direction, and these split plates are constituted in such a way that they can independently move up and down, respectively. Further, a plurality of thermometers 8a to 8h are provided, along the pallet-width direction, inside a wind box 6<SB>k</SB>corresponding to the position where exhaust-gas temperature is rising over 100°C in the exhaust-gas temperature distribution in the moving direction of the pallet. The split plates 4a to 4h are separately moved up and down so that the variation in the exhaust-gas temperature distribution in the pallet-width direction measured by the thermometers 8a to 8h becomes a prescribed value or below.
