There is disclosed a liquid ejecting apparatus including a liquid ejecting head having a nozzle and ejecting a liquid from the nozzle, a liquid supply passage which is connected with the liquid ejecting head, and through which the liquid is supplied to the liquid ejecting head, a gas discharge passage which is connected with the liquid supply passage at two different places, and through which a gas in the liquid supply passage is discharged, a gas-permeable film which is disposed at one of the two different places, constitutes a wall which separates the liquid supply passage and the gas discharge passage from each other, and allows gases to pass therethrough but does not allow liquids to pass therethrough, a shut-off valve which is disposed at the other of the two different places, and selectively placeable in an open state to communicate the liquid supply passage and the gas discharge passage with each other and a closing state to disconnect the communication between the liquid supply passage and the gas discharge passage, and a sucking device which lowers an internal pressure of the gas discharge passage by sucking the gas from the gas discharge passage.
