Abstract
[Object] To provide a method and apparatus for discharging a liquid material, which can solve the problems regarding the occurrence of a satellite and accuracy of a landing position. [Solving Means] In a method for discharging a liquid material in the state of a liquid droplet through a discharge orifice by applying inertial force to the liquid material, the method is characterized in comprising the steps of measuring a distance A from a lower end of the discharge orifice to a lower end of the liquid material having flowed out from the discharge orifice at the time when the liquid material having flowed out from the discharge orifice separates from the discharge orifice, and setting a distance B between the lower end of the discharge orifice and a work surface to be approximately the same as the distance A. An apparatus for carrying out the method is also provided.
