To provide a large-sized planter capable of being assembled at anywhere, simplifying its transportation and works, and also improving working efficiency by combining molded materials and the effective utilization of waste plastics, making them an assembling/disassembling type by piling them up as stages and fixing them with bolts and nuts.

This planter is characterized by producing molded members as the utilization of the waste plastics, installing recessed forms in the vicinity of the both ends of its molded article, boring a hole at the central part of the recessed forms, assembling the recessed forms to form a square by fitting the recessed parts, piling up the assembled members as stages to form a box shape, passing bolts through the holes at the center parts of the recessed parts and tightening with nuts.
