PURPOSE: A method for manufacturing sintered ore having excellent reducibility is provided to improve reduction index of the sintered ore by controlling constituents of magnesium oxide to be injected into the sintered ore as slag constituents. CONSTITUTION: The method for manufacturing sintered ore having excellent reducibility comprises the processes of adding 2.70 to 3.35 wt.% of serpentinite to sintered ore so as to maintain reduction index of sintered ore to 68 to 70%; adding 2.12 to 2.70 wt.% of serpentinite to sintered ore so as to maintain reduction index of sintered ore to 70 to 72%; or adding 3.35 wt.% or more, or 2.12 wt.% or less of serpentinite to sintered ore so as to maintain reduction index of sintered ore to 68% or less, or 72% or more, thereby securing reduction degradation index and rotation strength, which are quality control indices of sintered ore, and improving reduction index of sintered ore at the same time.
