To provide a fluid discharging pump capable of completely preventing a fluid from leaking to the outside a container.

The fluid discharging pump has a first supporting part 131a to be coupled with a coupling part 24 of a nozzle head 20, a second supporting part 131b of a flow-out valve seat member 121 to constitute a flow-out valve mechanism 12, and a tubular connection part 131c to urge the first supporting part 131a and the second supporting part 131b in a separating direction from each other on a tubular member 131 to constitute a leakage preventive mechanism 13. An abutting member 132 to constitute the leakage preventive mechanism 13 comprises a coupling part 132a fixed to a fixed part 25 of the nozzle head 20 and a lid part 132b formed on a lower end of the coupling part 132a. The tubular member 131 and the abutting member 132 are constituted in a left-as-it-is condition without load thereon so that the lid part 132b is assembled to a surface of a bent part 131d in an abutting manner at the connection part 131c of the tubular member 131.
