PURPOSE: A hydroponic culture device is provided to enable a user to work rapidly and conveniently when separating or fabricating beds from shelves. CONSTITUTION: Beds(20) are arranged on shelves(10), and germinate seeds. Beds are arranged together with an inlet(21a) and an outlet(21b) on a first external wall(21) which is aligned to the same direction in order to receive a nutrition solution from a supply pipe(40) and to simultaneously discharge the nutrition solution to a discharge pipe(50). A distribution tub(60) is connected to the supply pipe and the discharge pipe separately, and aligned along the first external wall of the beds. The distribution tub is divided into an upper supply channel(61) and a lower waterway(62). The inlet is inserted in a water supply protrusion pipe(61a) protruded from the upper supply channel, and provided with the nutrition solution. The outlet is inserted into a drainage hole(62a) punched on the lower waterway, and discharges the nutritional solution. The upper supply channel receives the nutrition solution from the supply pipe, and supplies the nutrition solution to the inlet. The lower waterway receives the nutrition solution from the outlet, and discharges the nutrition solution to the discharge pipe. A second external wall faces the first external wall. A Third and a fourth external wall meet the end portion of the second external wall perpendicularly, and face each other. A base is extended horizontally from the bottom of the first through fourth external walls. A cultivation domain(26) is gradually lowered from the first external wall toward the second external wall so that the nutrition solution supplied from the inlet flows to the second external wall. A drainage groove disembogues the nutrition solution passing through the cultivation domain to the outlet.본 발명은 베드(20)들의 제1외벽(21)에 급수구(21a) 및 배수구(21b)가 함께 배열 형성되고, 선반(10)에 급수구(21a) 및 배수구(21b)가 동일한 방향으로 배치되도록 하여, 공급관(40) 및 배출관(50)이 동일한 방향에서 급수구(21a) 및 배수구(21b)와 연통될 수 있도록 함으로써,
