1. A breast pump comprising:
a contact housing comprising a protruding part configured to correspond to a mother's nipple;
a cap connector coupled to cover the protruding part to form a first inner space;
a funnel connector on the cap connector to form a second inner space;
a linking pathway between the funnel connector and the cap connector and configured to link the second inner space of the funnel connector with the first inner space of the cap connector;
a storage housing comprising a coupling hole to correspond to the second inner space of the funnel connector and coupled with the contact housing;
a lid coupled to cover the second inner space of the funnel connector through the coupling hole of the storage housing;
a flow separation membrane configured to divide and separate the second inner space between the funnel connector and the lid;
an air pathway in the lid through which air flows into and out from a space between the lid and the flow separation membrane; and
an attachable pump module on the lid configured to suck the air between the lid and the flow separation membrane through the air pathway, wherein the attachable pump module is integrally coupled with the lid to be detachably coupled to the coupling hole,
wherein the flow separation membrane is directly coupled to an inner end of the coupling hole, and the lid is integrally coupled with the attachable pump module to be detachably coupled to an outer end of the coupling hole.
