PROBLEM TO BE SOLVED: To provide a liquid jetting device that can stably discharge air bubbles produced in a cleaning operation.SOLUTION: The liquid jetting device includes: a liquid storage member 3 in which liquid is stored; a liquid introduction unit 14 for introducing the liquid from the liquid storage member 3; and a liquid jetting head 2 for introducing the liquid from the liquid introduction unit 14 into a pressure chamber 39 via a liquid path, and jetting the liquid in the pressure chamber 39 by the actuation of a pressure generation means 32 from a nozzle 40 as a liquid droplet. The liquid introduction unit 14 has a liquid introduction path 15 for introducing the liquid from the liquid storage member 3, and an air bubble chamber 17 located downstream of the liquid introduction path 15, and for housing air bubbles mixed in the liquid. The air bubble chamber 17 and the liquid introduction path 15 are divided by a partition member 23, in which an inlet port 22 through which the liquid can flow from the liquid introduction path 15 to the air bubble chamber 17 is provided while facing the outer edge of the partition member 23. |
