<p>[PROBLEMS] A filling nozzle exhibiting a high flow straightening effect and forming a liquid flow having a stable circular cross-section. [MEANS FOR SOLVING PROBLEMS] The filling nozzle is formed by providing in a hollow nozzle body (2) a flow straightening member for straightening a liquid flow. A flow straightening plate (3) where a large number of fine holes (5) for allowing the liquid to pass through them are formed is used as the flow straightening member. At the edge of the exit opening of each fine hole (5) is provided with a chamfered section (7) as guidance means for guiding fine flows flowing from the adjacent fine holes (5), and the chamfered section (7) is on an exit-side surface (6) of the flow straightening plate (3).</p>
