1. A water-drip hose, in which an overlapped portion is formed by overlapping an outer film at one end portion of a resin film with an inner film at the other end portion of the resin film, and a main water flow path is formed inside the water-drip hose by a plurality of fusion splicing units fusedly formed on the overlapped portion, the water-drip hose comprising:
a plurality of first fusion splicing units, each first fusion splicing unit formed to have an upper fusion splicing line parallel to an end of the outer film, a lower fusion splicing line shorter than the upper fusion splicing line, and side fusion splicing lines of a smooth curved shape for connecting the upper fusion splicing line with the lower fusion splicing line; two second fusion splicing units respectively formed at a lower position between two neighboring first fusion splicing units of the plurality of first fusion splicing units in parallel to the lower fusion splicing line of each of the two neighboring first fusion splicing units at regular intervals, which forms three lower openings; and a third fusion splicing unit formed at an upper position between said two neighboring first fusion splicing units in parallel to the upper fusion splicing line of each of the two neighboring first fusion splicing units, which forms two upper openings. |
