PROBLEM TO BE SOLVED: To provide a hydroponic panel which is easily cleanable, sanitary without producing white powder on its surface, and capable of prolonging the usable period thereof, which prevents light from hitting culture fluid and from generating algae, and a plurality of which can be easily moved at one time.SOLUTION: A hydroponic panel has a flange portion 12 formed in a manner that an upper sheet 21 and a lower sheet 31 are adhered and sealed to each other on their peripheral edges, and also has a recess 33 formed in a manner that the lower sheet 31 is bent downward and the inside thereof is recessed to be protruded downward at a part surrounded by the flange portion 12. The hydroponic panel includes a bonded body of a quadrangle in plain view having a hollow between the upper sheet 21 and the lower sheet 31 in the recess 33, and a plurality of planting hole parts 13 are formed cylindrically in such a manner that the planting hole parts 13 pass through vertically in the hollow surrounded by the flange portion 12 on the peripheral edges.COPYRIGHT: (C)2016,JPO&INPIT【課題】清掃が容易で、表面に白い粉を生じず衛生的で、使用可能期間を長くでき、かつ培養液に光が当たるのを妨げて藻を生じ難くでき、さらには一度に複数を移動させ易い水耕栽培用パネルの提供を目的とする。【解決手段】上側シート21と下側シート31が周縁で接着シールされて該接着シールされたフランジ部12を周縁に有し、前記フランジ部12で包囲された部分には前記下側シート31が下方へ屈曲して内側が窪んで下方へ突出した凹部33を有し、前記凹部33で上側シート21と下側シート31間が中空となった平面視四角形の貼り合わせ体からなり、周縁のフランジ部12で包囲される中空部分には植え付け孔部13が上下に貫通する筒状で複数形成された構成とした。【選択図】図4
