PROBLEM TO BE SOLVED : To provide a hydroponics planting bed easy to clean, excellent in durability, capable of suppressing low a running cost of the whole of hydroponics, and excellent in adjusting properties of a nutritious liquid temperature. SOLUTION : This hydroponics planting bed 1 has a floating body structure in which a bottom wall 1a, a peripheral wall 1b which rises from the circumference of the bottom wall 1a, and many cylindrical planting parts 1c which are opened on the bottom wall 1a and rise upward are formed by a resin plate material or a metallic plate material. Thereby, the surface of the planting bed 1 is smooth, so it is possible to efficiently clean green alga and shorten a cleaning time, and the rigidity of the planting bed 1 is high, so it is extremely rare to cause damage, deficiency or breakage during cleaning green alga, and it is possible to improve the durability. Furthermore, the heat transfer property of the planting bed 1 is high, so it is possible to promote heat transfer between a nutrient liquid side and an air side, automatically manage a nutrient liquid temperature and an air temperature around a plant 20, and easily obtain an environment suitable for raising the plant 20.
