PROBLEM TO BE SOLVED: To provide a method of producing high strength sintered ore effective for improving the shatter index (SI) and the rate of disintegration during reduction (RDI) particularly in low slag ratio sintered ore reduced in the contents of SiO<SB>2</SB>and CaO regarding a method of producing sintered ore as one of the raw material for blast furnace charging. SOLUTION: In the method of producing high strength sintered ore, at the time of producing sintered ore comprising, by mass, <4.5% SiO<SB>2</SB>and 4 to 8% CaO, sintering treatment is performed using the blending raw material comprising≥50% iron ore having an apparent density of≥4.2 g/cm<SP>3</SP>, 5 to 15% mill scale and 0.8 to 4% MgO.
