Abstract
An electric breast pumpincludes a breast placement partat which a breast part including a breast and a nipple of a subject is placed and suction-pressure generating unitsandthat generate a suction pressure in the breast placement part. The suction-pressure generating unit generates a suction cycle including a plurality of different suction pressures. The suction cycle includes basic suction, increased suction with an increased suction pressure, and reduced suction with a reduced suction pressure. A suction pressure difference between a suction pressure increasing in the increased suction and a suction pressure reducing in the reduced suction is an equal pressure and is a pressure difference at a borderline at which a user perceives a change of a suction pressure. In the suction cycle, the basic suction, the increased suction, and the reduced suction are each repeated multiple times consecutively at an equal suction pressure.
