<P>PROBLEM TO BE SOLVED: To provide a droplet ejection method and a droplet ejection apparatus by means of which a state of a droplet ejected from a nozzle can be changed and a film formed of a liquid material can be formed on a receipt thing with high precision. <P>SOLUTION: A first ejection method or a second ejection method is chosen. In the first ejection method, a base material S is arranged between a droplet ejection head 2 which ejects a liquid material 10 having electrostatic chargeability as a droplet D from a nozzle 261 formed at a nozzle plate 26 having electrical conductivity and an electrode 31 which is arranged facing the droplet ejection head 2 in an ejection direction of the liquid material 10 and then the liquid material 10 is ejected as the droplet from the nozzle 261 in a state where potential difference is produced between the nozzle plate 26 and the electrode 31 and thereby the droplet D is supplied to the base material S in a mist state where the droplet is divided to two or more minute droplets smaller than the original droplet. In the second ejection method, the droplet of the liquid material 10 ejected from the nozzle 261 is supplied to the base material S in a state where potential difference between the nozzle plate 26 and the electrode 31 is smaller than that in the first ejection method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
