Provided is 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. The electric breast pump (1) is provided with a breast arrangement section (12) in which a breast region of a subject including a breast and a nipple is arranged and a suction pressure-generating section (10, 50) that generates 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 includes basic suction, increased suction in which the suction pressure is increased, and 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.L'invention concerne un tire-lait électrique et similaire permettant de tirer du lait maternel avec une pression d'aspiration appropriée pour une utilisatrice telle qu'une mère. Le tire-lait électrique (1) est pourvu d'une partie d'agencement de sein (12) dans laquelle une région de sein d'un sujet comprenant le sein et le mamelon est disposée et d'une partie de génération de pression d'aspiration (10, 50) qui génère une pression d'aspiration à l'intérieur de la partie d'agencement de sein. La partie de génération de pression d'aspiration génère un cycle d'aspiration intégrant une pluralité de pressions d'aspiration différentes. Le cycle d'aspiration comprend une aspiration de base, une aspiration renforcée au cours de laquelle la pression d'aspiration est accrue et une aspiration ré
