摘要： A fluid discharging device is provided with diaphragm members 20 and 30. The diaphragm member 30 being a valve member comprises an outlet 35 and a suction passage opening and closing portion 33, and can be moved forward and backward relative to the diaphragm member 20 being a pump member. The diaphragm member 20 comprises an outlet opening and closing portion 25 capable of opening and closing the outlet 35 and a measuring portion 26 capable of changing the volume of a measuring space 42. An outlet opening and closing means 50 opens and closes the outlet 35 by moving the outlet opening and closing portion 25 backward and forward relative to the outlet 35, and opens a liquid suction passage 40 by detaching the suction passage opening and closing portion 33 from the diaphragm member 20. A diaphragm moving means 55 changes the volume of the measuring space 42 by moving the measuring portion 26 forward and backward. The diaphragm member 30 closes the liquid suction passage 40 by pressing the suction passage opening and closing portion 33 against the diaphragm member 20 by its own elasticity.
