1. An electric breast pump comprising:
a breast placement part in which a breast part including a breast and a nipple of a subject is placed; and
a suction-pressure generating unit that generates a suction pressure in the breast placement part, wherein
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, and
the suction pressure difference is 2.5 kPa to 3.5 kPa.
