PROBLEM TO BE SOLVED: To provide a watering tube simplifying a production method, enabling watering for plants and still drop-like watering, and effectively usable for elevated cultivation which uses a cultivation tub having a small medium volume. SOLUTION: This watering tube 100 is formed from an upper surface sheet 1, a partition wall sheet 2 and a lower surface sheet 3 which are made of a rectangular synthetic resin film. The partition wall sheet 2 and a second seal part 32 are each punched with a plurality of distribution holes and water spray holes in the longitudinal direction. The partition wall sheet 2 and the lower surface sheet 3 are heat welded with each other in a first seal part 31 as both the ends in the longitudinal direction of the 2 sheets, and the partition wall sheet 2 and the upper surface sheet 1 are heat welded with each other on a side opposite to a side where the lower surface sheet 3 is heat welded with the partition wall sheet 2, in the second seal part 32 as both the ends in the longitudinal direction of the partition wall sheet 2 and the upper surface sheet 1. The width of the second seal part 32 is narrower than that of the first seal part 31, and drop holes are punched in an area where the first seal part 31 and the second seal part 32 are not superposed on each other.
