PROBLEM TO BE SOLVED: To eliminate the curing irregularity and the confusion in a next process of a concrete product such as a concrete block for construction and civil engineering when the concrete product is cured. SOLUTION: A plurality of the concrete products are stacked stepwise from above in a loading tower 3 to form one or more product sets. The product sets are successively housed in the curing chamber 7a of a curing apparatus 7 from the interior, and the respective product sets are cured in the curing chamber 7. In the curing process of the product sets, the mounting order of the product sets in the curing chamber 7 is reversed. After that, the product sets are conveyed in turn from the curing chamber 7 to a multi-stage fixed shelf 9, and the respective concrete products are delivered one by one to a conveyor 11 by an unloader 10. Between the product sets, each product set is brought into a first-in first-out state, and all of the concrete products are brought into the first-in first-out state in the product sets.
