PROBLEM TO BE SOLVED: To solve the problem that the prior manufacturing method of stone-finishing block increases a cost although the prior manufacturing method necessitates labor and many mold frames, the prior manufacturing method comprising placing natural stones on cast ready mixed concrete, making a small hole for draining on a bottom plate of a box type mold frame with the upper surface opened, arranging big stones on the bottom plate, inserting sand in the upper surface and pouring water on the upper surface to fasten them; placing small stones on the upper surface, inserting sand in the small stones, and pouring water again on the upper surface to fasten them, and casting the ready mixed concrete, curing and removing it. SOLUTION: The labor is eliminated since a suction-preventing material placed on the upper surface of a pallet acts as a bottom mold of a mold frame and the times of pouring water for fastening the natural stones and sand can be reduced. It is possible to reduce a cost since the ready mixed concrete can be immediately cast owing to soon water drainage in case of fastening, and the cured concrete can be removed from the mold owing to the absence of the bottom mold, be moved and be stacked for aging.
