PROBLEM TO BE SOLVED: To provide a tubular body for hydroponic cultivation of plants, which can suppress partial deviation of flow rate and speed of fluid in a cultivation cylinder, suppress variation in growth of plants, and improve cultivation yield. To do. SOLUTION: The mainstream tubular portion 10 has a flow passage FP through which a liquid required for plant cultivation flows, and has an opening 30 communicating with the flow passage and having a side wall formed with an opening 30 for inflow or outflow of the liquid. A first water guiding portion 50 that guides at least a part of the liquid flowing through the flow path in a circumferential direction on the inner wall of the mainstream tubular portion, and the first water guiding portion further extends from the inner wall of the mainstream tubular portion. A tubular body for hydroponic cultivation, which has a first guide surface 52 and which intersects the inner wall at an angle α with respect to the centerline CL of the mainstream tubular portion.
