[Problem] To provide an inexpensive manual breast pump that lessens fatigue while reducing the collision sound between a handle and a body. [Solution] A manual breast pump includes: a body 21 having a communicating part S4 that communicates with space surrounded by a hood placed on a breast； a diaphragm 30 that deforms to generate a negative pressure in the communicating part S4； and a handle 61 for operation that approaches and separates from the body 21 to deform the diaphragm 30, wherein a colliding part 40, against which at least the handle 61 and the body 21 collide before directly contacting each other when the handle 61 approaches the body 21, is provided in at least a region of any of the handle 61, the body 21, and the diaphragm 30, the colliding part 40 is integrally made of a same material as a material of a region 37 in which the colliding part 40 is arranged, and has a damper structure that absorbs an impulsive force or reduces propagation of the impulsive force and/or a cover structure in which the colliding part 40 is covered via a gap so as not to be exposed to an outside when making the collision.
