    Abstract: An electric breast pump 1 includes a breast placement part 12 in which a breast part including a breast and a nipple of a subject is placed and suction-pressure generating units 10 and 50 that generate a suction pressure in the breast placement part. The suction-pressure generating unit generates a suction cycle including a plurality of sucking operations. The suction cycle includes basic suction and increased suction with an increased suction pressure. A suction pressure difference that increases in the increased suction 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 and the increased suction are each repeated multiple times consecutively at an equal suction pressure. At least a last sucking operation in the suction cycle is extended suction having a longer suction time than those of other sucking operations.
