PROBLEM TO BE SOLVED: To provide a liquid ejector which can surely prevent the air from entering a liquid feeding path by normally pressuring the interior of the liquid feeding path for feeding a liquid from a liquid storage part to a liquid jetting head. SOLUTION: There are provided first valve parts 38 and 86-90 disposed between the liquid storage parts 9, 10 and the liquid feeding paths T5, T7-T11 to pass the liquid 1000 in only one direction from the liquid storage parts 9 and 10 to the liquid feeding path side; a second valve part 550 disposed between the liquid feeding paths T5, T7-T11 and the liquid jetting head 8 to feed the liquid 1000 from the liquid storage parts 9 and 10 to the liquid jetting head 8 and to stop the feeding of the liquid from the liquid storage parts 9 and 10 to the liquid jetting head 8 in accordance with an amount of the liquid at the liquid jetting head 8 side; and a liquid pressuring part 300 set at a position between the first valve parts 38, 86-90 and the second valve part 550 to pressure the liquid in the liquid feeding paths T5 and T7-T11 by storing the liquid and performing pressure accumulation.
