PROBLEM TO BE SOLVED: To provide a liquid supply device and a liquid-jet device discharging air bubbles from the inside of a filter chamber by pressurizing the filter chamber from the upstream side of the filter chamber. SOLUTION: The ink supply device 20 includes the filter chamber 40 disposed on the way of an ink supply path for supplying the ink from an ink cartridge side toward a recording head 24. In the ink supply device 20, the ink supply path is provided with a pressure chamber 37 on the upstream side of the filter chamber 40, the pressure chamber 37 is sectioned by a first flexible thin film 36 which is displaceable by receiving the pressure in the pressure chamber 37. The filter chamber 40 is sectioned by a second flexible thin film 39 to which a force is transmitted and also which is displaceable in accordance with the displacement of the first flexible thin film 36. In a state where the pressure chamber 37 and the filter chamber 40 are pressurized from the upstream side of the pressure chamber 37, the second flexible thin film 39 is displaced by the force transmitted from the first flexible thin film 36, toward a direction to reduce the volume of the filter chamber 40.
