Abstract:
1. A liquid droplet jetting apparatus which jets, onto an object, a main liquid droplet and a satellite liquid droplet which has a volume smaller than a volume of the main liquid droplet, comprising: a nozzle; a flying trajectory setting mechanism which sets a flying trajectory of the main liquid droplet jetted from the nozzle and a flying trajectory of the satellite liquid droplet jetted from the nozzle; a shielding body which shields a space in which the satellite liquid droplet jetted from the nozzle flies, wherein the shielding body comprises a side wall which surrounds the space entirely to suppress an airflow in the space; and a main liquid droplet trapping section which traps only the main liquid droplet, and which is arranged in the space at a position at which the main liquid droplet trapping section makes contact with the main liquid droplet jetted from the nozzle and has no contact with the satellite liquid droplet, wherein the shielding body further comprises a bottom wall which covers the space and which faces the object, wherein the bottom wall has a through hole formed therethrough, which allows only the satellite liquid droplet to pass through, and wherein an inner wall of the shielding body which defines the through hole is formed of an electroconductive material, and the inner wall is kept at an electric potential same as an electric potential of the satellite liquid droplet which is jetted from the nozzle.
