This invention provides an artificial nipple . The artificial nipple comprises: a nipple portion having a first curved surface, whose tip is provided with an opening portion ; a nipple body portion formed on the nipple portion , having a second curved surface, wherein the second curved surface of the nipple body portion is continuously extended from the first curved surface of the nipple portion , and wherein the second curved surface of the nipple body portion is significantly expanded as a part of the second curved surface goes away from the nipple portion ; and a base portion formed on the nipple body portion, wherein the base portion is capable of being attached to a container to house a drink. According to the present invention, the nipple body portion has a maximum outer diameter of 30 mm or more. According to the present invention, the nipple portion , measured by placing the base portion of the artificial nipple on a precise universal tester having a metallic pressing top made of a cylindrical shape with a radius of about 5 mm, to compress the maximum outer diameter of the nipple portion into the direction of the center thereof, has a nipple elasticity of 0.1 N to 0.8 N when the maximum outer diameter of the nipple portion is compressed by 20%, and of 1.0 N to 2.5 N when the maximum outer diameter of the nipple portion is compressed by 60%.
