PROBLEM TO BE SOLVED: To provide a breast pump capable of adjusting an increasing way of negative pressure according to a user. SOLUTION: A negative pressure generation means 10 in the breast pump 1 is provided with a motor 11, a diaphragm 12 of a thin film shape connected to the motor 11 to be vibrated by rotating and driving the motor 11, a pump space 13 for increasing/decreasing the volume of the diaphragm 12 according to the vibration of the diaphragm 12, a sectioning part 14 for sectioning and forming the pump space 13 together with the diaphragm 12, and a relatively moving means 17 for relatively moving the sectioning part 14 in relation to the diaphragm 12. The relatively moving means 17 is constituted of a stroke mechanism 18 for stroke movement of the sectioning part 14 in relation to the diaphragm 12 and an operation part 19 capable of operating the stroke mechanism 18 from the outside.
