To provide a greening shelf using rain water, capable of making the best use of the rain water, by integrating constitutions for utilizing the rain water such as water collection, water split, storage, water supply (for example, water spray).

This greening shelf 1 using the rain water includes a plate body 4 between adjacent support columns 3, 3, a vegetation support body 5 for supporting a plant P under a condition along at least one face of the plate body 4, between the adjacent support columns 3, 3, and a vegetation container 6 allowing vegetation of the plant P in an under side of the vegetation support body 5, and the rain water is supplied to the vegetation container 6 to make the plant P grow in the greening shelf 1. The greening shelf 1 includes a rain water collecting means 10 for collecting the rain water, a rain water splitter 11 for splitting the collected rain water into a drainage side and a storage side, a rain water storage tank 13 having an introducing port 12 for introducing the rain water split into the storage side, and a water supply means 15 having a water supply flow channel B communicated with a leading-out port of the rain water led out from a leading-out port 14 formed in the rain water storage tank 13, to supply the rain water to the vegetation container 6.
