Disclosed is a separate type nursing bottle, which includes two separate bodies so as to allow a user to cleanly wash the bodies in a convenient manner. The separate type nursing bottle includes an upper body, a lower body, and a connector. The upper body has a pipe-shape and includes screw parts formed at an outer circumferential surface of one end of the upper body and at an outer circumferential surface spaced a predetermined distance from another end of the upper body, respectively. The lower body has a bowl-shape, has an open side engaged with an outer circumferential periphery of the other end of the upper body, and includes a locking jaw formed along an outer circumferential periphery of one end of the open side. The connector has a pipe- shape, has a locking jaw so as to allow the connector to be assembled with an outer side of the upper body while one end of the connector is locked in the locking jaw of the lower body, and also has a screw part engaged with the screw part of the another end of the upper body. The upper body from the screw part to the other end is slanted toward a central axis of the upper body so that an inner diameter is smaller toward the other end. The lower body is made from material, which is more flexible than material of the upper body, so as to allow a shape of the lower body to be easily changed. As a result, there is a sanitary advantage in that the user can cleanly wash the interior of the nursing bottle, and convenience can be provided to the user while washing the bottle.
