Zusammenfassung:	PURPOSE: To form a liquid drop having an uniform density and a constant particle size and improve the precision of volume measurement by generating an electric field in the outflow port of a liquid material supplying member to regulate the particle size of the liquid drop. CONSTITUTION: An outflow port 3 for a liquid maternal 13 formed into a nozzle having a diameter of about 1.5mm by use of an electric conductive material, so that a specified number of liquid drops are guided into a vessel situated under the outflow port 3 according to a desired liquid quantity. A nozzle 2 having the outflow port 3 is electrically connected to the first electrode 5 of a high voltage source 7, the second electrode 6 of the power source 7 is connected to a metal grid electrode 4 provided opposite to the outflow port 3 to generate a strong electric field within the range of the outflow port 3, and the particle size and mass of a liquid drop 8 is controlled by the high voltage applied to the outflow port 3 and the electrode 4. According to such a structure, when the voltage is enhanced to about 10kV' per 1cm distance between the outflow port 3 and the electrode 4, the liquid drop diameter can be reduced less than 1mm.
