Provided is an inexpensive manual breast pump that allows reduction in noise of an impact between a handle and a body portion while also allowing suppression of fatigue. The manual breast pump is provided with: a body portion (21) that includes a communicative connection part (S4) communicatively connected to a space enclosed by a hood for being fitted on a breast； a diaphragm (30) that is deformed so as to cause negative pressure to be applied to the communicative connection part (S4)； and an operation handle (61) that comes near the body portion (21) and comes apart therefrom so as to deform the diaphragm (30), wherein an impact part (40) that, when the handle (61) comes near the body portion (21), undergoes an impact before the handle (61) and the body portion (21) come into contact with each other, is provided in any of regions of the handle (61), the body portion (21), and the diaphragm (30), and the impact part (40) is integrally formed by use of the same material as that in the region (37) in which the impact part (40) is arranged, the impact part (40) having: a damper structure for absorbing the impact force of an impact or inhibiting transmission of the impact force； and/or a cover structure with which the impact part (40) is covered with a gap interposed therebetween so as not to be exposed to the outside.La présente invention concerne un tire-lait manuel peu coûteux qui permet de réduire le bruit d'un impact entre une poignée et une partie de corps tout en permettant également la suppression de fatigue. Le tire-lait manuel est équipé: d'une partie de corps (21) qui comprend une partie de connexion de communication (S4) reliée en communication à un espace entouré par un capot destiné à être ajusté sur un sein； d'une membrane (30) qui est déformée pour entraîner l'application d'une pression négative à la partie de connexion de communication (S4)； et d'une poignée d'actionnement (61) qui se rapproche de la partie de corps (21) et s'en éloigne de manière à dé
