PROBLEM TO BE SOLVED: To make a small and simple structure easy to purify by providing a reserve section for reserving breast milk from a milking section, a minus pressure release means for releasing one part of a minus pressure produced in the milking section during producing the minus pressure caused by a minus pressure produce means for producing the minus pressure in the milking section at a certain time period. SOLUTION: A breast pump 1 is a diaphragm-type diaphragm pump milking device. When a switch 41 is on, a minus pressure is pulsatively produced by a motion of a driving section 4 in a milking section 2, precisely in the milking section 2 and a reserve section. Produced minus pressure massages the breast in a horn-like section 22 to squeeze breast milk. Squeezed breast milk is transferred through the horn-like section 22 and a cylindrical section 24 to a lid section 26. The lid section 26 is detachably assembled to the reserve section 3 such as a bottle, and the breast milk is finally reserved in this reserve section 3 thereby. The breast milk reserved in the reserve section 3 can be easily taken out of the reserve section 3 by taking out the lid section 26 of the milking section 2.
