PROBLEM TO BE SOLVED: To provide a production method of sintered ore, with which the sintered ore having uniform quality from the upper layer part to the lower layer part can be obtd. when sintering a raw material having >=45% blended ratio of high crystallization where ore is sintered. SOLUTION: In the producing method of the sintered ore with a Dwight Lloyd type sintering machine, when the sintering raw material 1 having >=45% blending ratio of the high crystallization water ore is sintered, the sintering raw material 1 is charged in the state of disposing plural flat plates 3 arranged at the tip parts of gas venting bars 13 in the width direction of a pallet 6 at the position of 0.2-0.6 times the thickness of a raw material piling layer 4 from the lower part of the raw material piling layer 4 toward the advancing direction of the pallet 6. Further, after compressing and compacting the surface of the raw material piling layer 4 by 10-30 mm with a compacting roll 3 having the pallet width arranged at the outlet side of a cut-off plate 11, the sintering is executed.
