To manufacture a water collection implement receiving leakage water from a water leakage section and draining so as to be manufactured in a simpler structure and costlessly and make the drain pipe hard to come off and make easily changeable the diameter or the like of the drain pipe if necessary.
A cylinder 3 made of a flexible material is fixed to the rear face side of a water stream opening h part of a flat shaped flexible sheet 2 where the water stream opening h is formed in a specified position to connect the cylinder inside to communicate with the water stream opening h, The insert part 4s of the joint member 4 is made freely insertable and at the same time, a drain horse 5 made of a flexible material is made freely connectable to the insert part 4s of the other side. When the peripheral part of the flexible sheet 2 is fixed with a margin of the leakage section, it is fixed in the tension of the sheet 2 to the periphery of a water leakage part.
