To provide an electric breast pump and the like that make it possible to pump breast milk at a suction pressure suitable for a user such as a mother.SOLUTION: An electric breast pump 1 comprises: a breast arrangement section 12 in which a breast region of a subject including the breast and the nipple is arranged； and a suction pressure-generating section 10, 50 that generates a suction pressure within the breast arrangement section. The suction pressure-generating section generates a suction cycle comprising a plurality of different suction pressures. The suction cycle comprises a basic suction, an increased suction in which the suction pressure is increased, and a reduced suction in which the suction pressure is reduced. The amount by which the suction pressure is increased in the increased suction and the amount by which the suction pressure is reduced in the reduced suction are the same amount of pressure, and these amounts are a pressure difference corresponding to a threshold at which the user senses the change in suction pressure. The basic suction, the increased suction, and the reduced suction are each repeated at the same suction pressure in succession multiple times in the suction cycle.SELECTED DRAWING: Figure 3【課題】母親等の利用者にとって適切な吸引圧力で搾乳を行うことができる電動搾乳器等を提供すること。【解決手段】対象者の乳房及び乳首等の乳房部を配置する乳房配置部１２と、乳房配置部内に吸引圧力を発生させる吸引圧力発生部１０、５０と、を備え、吸引圧力発生部は、複数の異なる吸引圧力からなる吸引サイクルを発生させ、吸引サイクルは、基本吸引、吸引圧力を増加させた増加吸引と、吸引圧力を減少させた減少吸引を含み、増加吸引において増加する吸引圧力と減少吸引において減少する吸引圧力差は同一圧力であって、利用者が、吸引圧力の変化を感知する境目の圧力差であり、前記吸引サイクルが、基本吸引、増加吸引及び減少吸引を、それぞれ同じ吸引圧力で連続して複数回繰り返す電動搾乳器１。【選択図】図３
