PURPOSE: Provided is a bottle stopper with a built-in straw to improve the structure of the bottle stopper and to help users to drink the content in the bottle more conveniently by using the straw built in the bottle stopper. CONSTITUTION: The bottle stopper with a built-in straw has a protruded inside(101) to ensure that the bottle and the stopper are tightly locked to each other. Also, a fixing projection(102) is formed inside the stopper. The entrance of the fixing projection(102) is broader than an inside diameter of the straw, and the waist of the fixing projection(102) is narrower than the straw so that the straw is firmly fixed to the stopper. It is also possible to make the entrance of the fixing projection(102) smaller than the inside diameter of the straw, and make the waist of the fixing projection(102) greater than the inside diameter of the straw. An air outlet vent (103) for discharging the air from the inside of the straw is formed on the fixing projection(102).
