A fluid pressure-feeding device includes: a balloon pump of a bag shape that is elastically expandable, contractible and deformable, and defines a pump chamber inside; and a flow path unit that includes at least a portion of a flow path communicating with the pump chamber. The balloon pump and the flow path unit are integrally arranged. The flow path includes a supply path that supplies a fluid to the pump chamber, and a discharge path that discharges the fluid from the pump chamber. The discharge path has a greater pressure loss than the supply path.
