A discharge amount regulating method, a discharging method, and a discharging device, where liquid drops are discharged as liquid drops of precise amounts. In a regulating and a discharging method, a discharge amount of a liquid drop discharged from a discharge opening communicating with the tube is regulated by advance and stop of a plunger sliding in a tube while being in close contact with an inner wall surface of the tube. Moving speed from time at which the plunger that advances starts deceleration to time at which the plunger stops is regulated so that liquid drops discharged from the discharge opening have a fixed amount at every discharge. A discharge device is a device for discharging a liquid material, and has a tube, a plunger sliding in the tube while being in close contact with the inner wall surface of the tube, a discharge opening communicating with the tube and discharging a liquid material as flying drops, and control means for controlling operation of the plunger. The control means controls the speed of the plunger from time at which the plunger that advances starts deceleration to time at which the plunger stops.
