Cooling device for sintered ore

Provided is a compact cooling device for sintered ore which has good cooling efficiency for sintered ore, is capable of large-volume processing, has high heat recovery efficiency, and with which dust is easily collected. In this sintered ore cooling device (1) one side surface of a cooling vat (3) is provided with a gas passage section that stops sintered ore but allows gas to pass through, and the portion of the other side surface of the cooling vat (3) which faces the gas passage section is a ventilation section that stops sintered ore but allows air to pass through. The length in the height direction of a cooling region (defined by the region sandwiched between the gas passage section and the ventilation section) is at least 1/2 the height of the cooling vat (3), the thickness of the cooling region is 1/6 - 1/4 the height of the cooling vat (3), and the upper end of both the inner circumferential and outer circumferential side walls of the cooling vat (3) is located at a height of no less than 1.2 times th
