A straw including a straw body defined therein with a passage extending throughout the length of the straw body, a bellows portion formed at a desired portion of the straw body, the bellows portion having a desired length, and a tube arranged in the bellows portion and integrally formed with the bellows portion, the tube having a desired elasticity and being configured in such a fashion that opposite inner surface portions thereof are in close contact with each other in a bent state of the bellows portion by a desired angle, thereby closing the passage of the straw body. The straw not only has a function capable of allowing the user to easily adjust the orientation of the straw, thereby easily adjusting the spouting direction of the straw upon drinking the beverage, but also has a valve function for selectively opening and closing the straw, as desired, thereby being capable of adjusting the flow rate of the beverage being spouted through the straw while keeping the taste and aroma of the beverage, preventing foreign matters from being introduced into the container, and preventing the beverage from being unintentionally spouted from the container due to an impact applied to the container.
