1. A method for applying a viscous material by lowering a nozzle to a lowered position and applying a viscous material ejected from an ejection port formed at a tip end of the nozzle to an application target,
said method comprising: performing an adhering amount detecting process a plurality of times, the adhering amount detecting process comprising:
lowering the nozzle to a trial application position;performing a trial application to apply the viscous material to a trial application surface disposed on an application stage; anddetecting an amount of the viscous material adhering to the nozzle, after the trial application is ended and the nozzle begins to elevate from the trial application position; determining whether a difference between maximum and minimum values of the amounts of the viscous material adhering to the nozzle detected the plurality of times exceeds a threshold; and setting, if it is determined that the difference does not exceed the threshold, the lowered position of the nozzle with respect to the application target such that a gap between the nozzle at the lowered position and an application surface of the application target coincides with a gap between the nozzle at the trial application position and the trial application surface. |
