PURPOSE: A nursing bottle is provided, to make the air be introduced into the bottle automatically when a baby sucks milk. CONSTITUTION: The nursing bottle comprises a neck part(403) which is provided with a screw thread(405) in the outer circumference, and at least one groove(402) being an air path in the inner corner connected with the horizontal face(401) and the inner circumference(404); and a body part(408) which is cylindrical and whose bottom is closed. When a nipple(200), a stopper(300) and a bottle (400) are combined, the round horizontal part(204) of the nipple is closed to the neck to isolate the air path(402); when a baby sucks milk, the pressure of the inside of the bottle is lowered, the position adjacent to the inside of the neck of the horizontal part(204) is bent in lower direction, the outer rim(205) of the horizontal part(204) is bent in the upper direction with supporting of the neck corner, and which opens the air path(402); and when a baby stops sucking milk, the air path(402) is closed by the restoring force of the nipple.
