Abstract: Disclosed is a milking apparatus that prevents extracted mother's milk from flowing into a pump, thereby keeping the mother's milk hygienic. A first space in a milking head communicating with a milking cup and a second space communicating with a space in a rubber bulb are separated from each other by a partition film, and air in the rubber bulb is exchanged solely between the interior of the rubber bulb and the second space, which is surrounded by the partition film and an upper cover portion of the milking head.
