PROBLEM TO BE SOLVED: To provide a method for manufacturing sintered ore using a high-phosphorus ore with less reduction of sintering productivity. SOLUTION: In this method for manufacturing the sintered ore, the high-phosphorus ore having >0.1 mass% P component is used by being blended with ores for raw materials for sintering, and the proportion of the amount of Al<SB>2</SB>O<SB>3</SB>contained in a fine powder part as fine as≤0.25 mm in the high-phosphorus ore to the mass of the whole high-phosphorus ore is made to≤2.2 mass%. By this method, deterioration in the flowability of melt when melting the fine powder part can be suppressed and air permeability during sintering can be secured, and as a result, extension of sintering time can be prevented.
