A method for manufacturing reduced iron briquettes, wherein reduced iron obtained by a direct reduction method is made into briquettes using a briquette machine, and whereafter the hot briquettes are subject to gradual cooling at a cooling rate in the range of 150 DEG C. to 250 DEG C. per minute using water spray. The reduced iron briquettes thus obtained are (a) less prone to breakage break during storage and transport; (b) less prone to degeneration into powder accompanying such breakages etc.; and (c) also display an excellent degree of metallization. Hence, the loss in weight during storage and transport can be reduced, and the harmful effects caused by dust to the transport vehicles, ships, loading/unloading equipment, and operators of the same can be reduced. Also, since the number of breakages is reduced, there is also a reduction in the amount of any re-oxidation of the reduced iron which tends to occur at newly exposed faces, whereby a product of more consistent quality can be obtained.
