PROBLEM TO BE SOLVED: To provide a spray device which can achieve downsizing, facilitate management and manufacture, and reduce the manufacturing cost.SOLUTION: In a spray device for spraying a liquid, a connector 27 is fixed to a supply port 26 of a tank 2, and a pump inlet pipe 31 projected outward from a casing 33 of a pump 3 is fixed to a water absorption port 27a provided integral with the connector 27, thereby fixing the pump 3 to the tank 2. Thus, the need of a member for connecting or fixing the tank 2 and the pump 3 to each other is eliminated. Further, connecting portions between the tank 2 and the pump 3 are integrated with the connector 27, so that leakage of the liquid can be easily confirmed. Further, it is not necessary to provide the tank 2 with a screw hole or the like for fitting the pump 3.
