Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of producing sintered ore where productivity and the yield of products are not reduced even when maramanba ore of high crystallization water and low gangue containing much fine powder is used as the raw material for sintered ore. SOLUTION: The sintered ore is produced by blending maramanba ore containing, by mass, ≥3.0% crystallization water, ≤4.0% SiO2, and ≥20% fine powder with a particle diameter of ≤0.25 mm with ore having a specific surface area of ≥3 m2/g, and in which the relation between the ratio A1(mass%) of particles with a particle diameter of 3 to
