PROBLEM TO BE SOLVED: To improve sprinkling capacity by forming small feeding holes and sprinkling holes in an inner tube layer and an outside cover layer respectively and preventing the close adhesion between the inner tube layer and the outer cover layer by a braid reinforced layer in a hose of a three-layer structure formed of a synthetic resin composition. SOLUTION: This sprinkling hose used for greenhouse cultivation, open-field cultivation, etc., is formed by concentrically providing a synthetic resin inner tube layer 2 having, e.g. the dimension of the inside diameter 17.0 mm and the outside diameter 20.0 mm and a plurality of streak projections 3 formed longitudinally at equal pitches, a braid reinforced layer 4 formed by braiding polyester fibers by a braider, and an outer cover layer 5 having, e.g. the dimension of the inside diameter 17.0 mm and the outside diameter 21.8 mm. In this case, the outer cover layer 5 is in contact with the braid reinforced layer 4 but in no contact with the projections 3 of the inner tube layer 2 and a clearance for letting fluid such as fluid fertilizer pass through is secured between the inner tube layer 2 and the outer cover layer 5 uniformly disperse the fluid.
