The invention provides an artificial nipple and a feeding bottle with the artificial nipple. The artificial nipple and the feeding bottle can adjust proper lactication time or drink flow for an infant by a simple method. The artificial nipple (2) is provided with an artificial nipple body (7), a first ventilation component (5), and a second ventilation component (6). The first ventilation component (5) is provided with a plurality of ventholes (53,54,55) which are different in opening area in the same differential pressure. The second ventilation component (6) is provided with a venthole (67). The artificial nipple (2) is installed on the feeding bottle body holding drink. The artificial nipple and the feeding bottle are characterized in that through optionally communicating the venthole (67) of the second ventilation component (6) relative to the plurality of ventholes (53,54,55) of the first ventilation component (5), gas flow flowing into the feeding bottle (1) from the external through the communicated ventholes can be adjusted.
