To increase the durability and workability of a concrete depositing mold and improve the appearance of concrete after depositing.

A synthetic resin cover 1 of a concrete deposing mold is put on a concrete depositing mold 50. Because the synthetic resin cover 1 of the concrete depositing mold shields the moisture and alkali components of the deposited concrete, the concrete depositing mold 50 is hardly corroded. Also, because dry concrete hardly adhere to the synthetic resin cover 1 of the concrete depositing mold, a scrape-off operation becomes almost unnecessary, and the concrete depositing mold 50 is not broken. As a result, the service life of the concrete depositing mold 50 can be increased. In addition, the operation for removing the adhered concrete becomes almost unnecessary and a working load is reduced. Then, through the smoothness of the surface of the synthetic resin cover, the appearance of the deposited surface of concrete can be improved, and the finish of depositing equal to or higher than a new concrete panel or a painted concrete panel can be obtained.
