PROBLEM TO BE SOLVED: To provide a nozzle device that prevents air from being drawn when liquid is supplied into a closed-bottomed container or restrains to such a degree as to cause any problem. SOLUTION: The nozzle device for supplying liquid to the closed-bottomed container has an installation tube 10 for installation on a discharge opening of a liquid supply device, a bottom wall 21 for covering the lower end of the installation tube, and a discharge tube 22 extending downward from the bottom wall 21. The discharge tube 22 has a large number of introduction holes 23 extending from the upper side of the bottom wall 21 to the inside of the side wall of the discharge tube 22 and having the lower ends staying in the side wall. Also, the discharge tube 22 has formed in it discharge grooves 24 open to the outer peripheral surface of the discharge tube 22 and communicating, inside the discharge tube 22, with the introduction holes 23. In a method of supplying liquid to the closed-bottomed container, the liquid is radially discharged from the nozzle device installed on the discharge opening of the liquid supply device, which causes the liquid to be in contact with the side wall of the container and drop along the side wall.
