A liquid ejecting apparatus has a liquid ejecting unit and a negative pressure regulating unit provided between passages connecting the tank to the liquid ejecting unit, regulates fluid pressure of liquid flowing into the liquid ejecting unit. The negative pressure regulating unit includes a negative pressure chamber whose internal pressure is regulated within a predetermined range, and a discharging passage for discharging liquid stored in the negative pressure chamber from the negative pressure regulating unit. The discharging passage has an outlet disposed in an upper portion of the negative pressure chamber in a direction of gravity, a bubble accumulation portion connected to the outlet and having a space above the outlet in the direction of gravity, and a passage guiding liquid flowing from the outlet to a discharging port opened in a bottom of the negative pressure regulating unit.
