To provide a new fluid discharge pump, which can prevent a liquid drop by making a ball value keep a loose movement over a term as long as possible after the fluid is discharged.

The fluid discharge pump makes a press head, which is installed to a vessel body containing the fluid, move forwards so that the fluid reciprocating in a pipe body can be discharged from an opening part of a flow passage in the press head as reciprocation of the press head in a pump part installed to the vessel body, wherein the pipe body has a spiral ditch and the ball valve which are formed on the inner wall side near the opening part of the pipe body introducing or removing the fluid in the pipe body in or from the flow passage, the ball valve, part of which fits in the spiral ditch, can move loose in the spiral ditch if the fluid in the pipe body is removed.
