摘要：
A liquid filling apparatus includes a discharge head having a cavity for storing liquid, a nozzle communicated with the cavity, and a discharge device for discharging liquid stored in the cavity through the nozzle. In addition, the apparatus includes a liquid supply section which supplies the liquid to the nozzle of the discharge head by contacting the liquid with the nozzle, and a suction device connected to a cavity side of the discharge head, which draws liquid supplied from the liquid supply section to inside the cavity, by suction from the nozzle via the cavity.
