In production of sintered ore, an aqueous solution is added to iron ore powder and an auxiliary material, the iron ore powder and the auxiliary material are kneaded to form a mixture, and the mixture is granulated to form granules, wherein the aqueous solution contains a water-soluble compound reacting with the iron ore powder to form a reaction product having a melting point of 1200° C. or lower.
