PROBLEM TO BE SOLVED: To provide a liquid supply pipe which includes a plurality of liquid supply holes provided in a bottom part along a longitudinal direction and enables a liquid supply amount from the liquid supply holes to be uniformized, and which facilitates flow rate adjustment, and a liquid supply structure with the liquid supply pipe, for plant factory, and to provide a liquid supply pipe which enables contamination inside the pipe and clogging of liquid supply holes to be prevented, and a liquid supply structure with the liquid supply pipe, for a plant factory.SOLUTION: The liquid supply pipe has: a pipe body； and a plurality of liquid supply nozzles which are provided in a bottom part of the pipe body along a longer direction of the pipe body, and which supply liquid flowing through the pipe body to the outside of the pipe body. In the liquid supply pipe, the liquid supply nozzle has a protruding part protruded to the inside of the pipe body, and liquid is supplied from a supply hole provided in an upper end of the protruding part to the outside of the pipe body.SELECTED DRAWING: Figure 3【課題】長手方向に沿って底部に複数設けられる給液孔からの給液量を均一にすることが可能であり、流量調節が容易な給液パイプ、及び、該給液パイプを備えた植物工場用の給液構造を提供する。また、管内の汚れ、及び、給液孔の詰まりを防止することが可能な給液パイプ、及び、該給液パイプを備えた植物工場用の給液構造を提供する。【解決手段】パイプ本体と、パイプ本体の長手方向に沿ってパイプ本体の底部に複数設けられ、パイプ本体を流れる液体をパイプ本体の外側へと供給する給液ノズルと、を有し、給液ノズルは、パイプ本体の内側に突出した突出部を有し、該突出部の上端に設けられる送給孔から液体がパイプ本体の外側へと供給されることを特徴とする給液パイプとする。【選択図】図３
